3-Pyridinecarboxylic acid, 5-bromo-6-hydroxy-

The chemical properties of this product are also very important, related to its use, performance and existence. Today's ancient classical Chinese style imitating "Tiangong Kaiwu" is described by you.
This product has many stable properties, and it does not change easily when it encounters normal temperature and pressure. It is less oxygenated in the air. If gold is firm, it is not easy to rust. And it is also less soluble in water. If a stone is in the abyss, it will exist quietly and alone, and will not be transformed into flow waves.
When it encounters strong acid and alkali, it will change. Acids, such as sulfur and nitrate, meet with it, or respond to it violently. At the right time, there is gas coming out, and the color and taste are all different, like the rise of fog, the rise of gas, and the temperature changes, or the heat burns the hands. Alkali, if the alkali of sodium and potassium is combined with it, there is also a reaction, and its quality is gradually changed, or soft or dissolved, like ice when met with fire, gradually turning invisible.
And it also responds to heat. Heated to a certain degree, or melted into a liquid, the state is like the flow of water, and the shape changes with the device. Even hotter, it vaporizes into steam, scattered in the air, like a cloud floating, and cannot be caught. Then it cools again, or condenses into solids, and the shape is like the original form, this reversible change is also.
And this product, when combined with various things, often becomes a new quality. Combine with a certain metal, or increase its strength, if the carbon of steel is added, it is strong but not folded; combine with an organic person, or change its properties, such as the addition of paint, which is bright and lasting. Its chemical properties are so complicated, but they all follow the rules of heaven and earth, the principles of yin and yang, and cannot be messed up by human beings. Good knowledge of its nature, it can be used wonders, which are of great benefit to work, agriculture, and medicine; if you don't know its nature and use it indiscriminately, it will not be far away, just like the misuse of medicine, hurting people invisibly.

The main users of this product are covered by the following ends.
First, it helps a lot in farming and mulberry affairs. Ancient farming was heavy and abnormal, and although human and animal strength was diligent, the efficiency was limited. This product can be used in cultivated land, sowing, and irrigation. For example, when plowing the land, ordinary farmers turn the land by digging, which takes time and effort, and there is very little land ploughed in one day. If this product is used, its force is large and fast, which can quickly turn the fields and lay a good foundation for sowing and raising seedlings. When sowing, seeds can also be evenly sown according to the time and amount, so as not to lose density. When irrigating, it can lead canal water to the field, precisely control the amount of water, so that the seedlings can be nourished by water, without the worry of drought and flood, help the harvest, and protect the people's food and clothing.
Second, in civil construction, the function is significant. To build palaces, city walls, bridges and other projects, it is necessary to move huge trees and boulders. Manual handling is difficult and easy, and it is easy to cause casualties. This product can be used on heavy objects, or traction, or lifting, so that the wood and stones can be moved orderly. If when building a city, the boulders need to be placed on the city wall. With this product, it can be easily lifted to the designated place, saving a lot of manpower, speeding up the construction process, making the city strong and ensuring peace.
Third, it has many benefits in transportation. In ancient times, land transportation depended on vehicles and horses, and water transportation depended on boats. However, in the face of dangerous mountains and rivers, the road is rugged, and transportation is often blocked. This product can open up passages in difficult places, or drag vehicles and boats to make them travel unimpeded. If rivers flood and bridges collapse, you can also use this product to quickly build temporary passages to ensure the circulation of personnel and materials and maintain exchanges between the four sides.
Fourth, it has an extraordinary effect in military expeditions. On the battlefield, the use of equipment is related to victory and defeat. This product can be reformed into a siege tool, such as a catapult, which can throw boulders far away and destroy enemy city walls. It can also be used to carry grain and grass baggage to ensure the supply of the army. During the march, when encountering mountains and rivers, you can use this product to quickly build bridges and build roads, so that the army can move quickly, surprise, overcome the enemy, and ensure the stability of the country.

The method of making a certain product is a crucial matter. The process contained in Guanfu's "Tiangong Kaiwu" is very delicate and can be used for reference.
If you want to make this product, the first material should be selected. It is advisable to choose materials with excellent texture and good character. For example, "Tiangong Kaiwu" says: "When making a good tool, you must first choose good materials." The quality of materials is related to the foundation of product quality. When selecting materials, when carefully observing their color, texture, hardness and other characteristics, it is necessary to make them meet the requirements of product production.
The second time is the processing method. The processing steps need to be followed in sequence and cannot be disordered. Or calcined to change its properties. " "When calcining, it is crucial to control the heat." Too much or not enough heat will affect the quality of the product. After calcination, there may be hammer forging to make the material dense and solid. The force of hammer forging should also be moderate. If it is too strong, the material will be vulnerable, and if it is too light, it will be difficult to form.
Furthermore, the forming technology cannot be ignored. According to the shape of the product, it can be cast or cut to give it its initial appearance. Casting requires a sophisticated mold and the precision of the mold to determine the shape of the product. Cutting requires skilled craftsmen and precise cutting to make the product line smooth and proportional.
After that, there is still work to decorate. Or polish to make the surface of the product smooth and delicate, and feel pleasant to the touch; or apply color to give the product a suitable color according to its use and aesthetics. The power of modification can add a lot of color to the product and enhance its value.
All these combined methods require the dedication and proficiency of craftsmen. As advocated in "Tiangong Kaiwu", keep improving, in order to produce high-quality products. From the careful selection of materials, to the fineness of processing, molding and modification, every step is about success or failure. Only interlocking can achieve a good product.

Looking at this product in the market, it is quite difficult to determine its price. The situation in the market is complicated, and various factors are intertwined to affect it, so the price is unpredictable.
When you taste the ancient merchants, when you make a living, you must carefully observe the changes in the situation, supply and demand, and then decide the price. In today's world, the same is true. The price of this product may vary due to the quality of the material and the simplicity of the craftsmanship. If the material is high-quality, it is not easy to obtain, and the craftsmanship is exquisite, and the carving is meticulously crafted, the price should be very high; on the contrary, if the material is ordinary and the craftsmanship is crude, the price may be slightly inferior.
In addition, the supply and demand of the city also have a great impact on the price. If the product is well-liked by everyone, and there are many people who want it, but there are few people who supply it, the price will increase; if the supply exceeds the demand, everyone will regard it as normal, and the price may decline.
Furthermore, the prestige of the brand and the situation of the competing products also affect its price. For a well-known brand, its products are often praised for increasing the price; and there are many competing products, each trying their best to compete for the market, and the price may fluctuate.
Roughly speaking, the price of this product can be as low as tens, and as high as hundreds, or even thousands. However, this is only an imaginary number, and the actual price still needs to be determined according to the actual situation of the market and the changes of time, and cannot be generalized.

The safety precautions related to a certain product are related to the personal safety of the user and the stable operation of the product, and should not be ignored.
First, read the instructions carefully before use. The product description contains structure, performance, operation method and safety points. If it is not followed, it may cause operation errors, causing failure, damage, and even endangering personal life. Just like driving, not reading the manual, not knowing the warning, rushing on the road, and there are many hidden dangers.
Second, the environment is suitable. The product has requirements for the use environment, temperature and humidity, ventilation, dust, etc. All have an impact. If electrical appliances are used in damp places, the components are easy to rust and short-circuit; if precision instruments are used in high temperature environments, the accuracy will decrease. Such as the ancient good bow, it must also be properly stored in a suitable place, otherwise it will be easy to fold.
Third, standardize the operation. Operate strictly according to the process, without violating the rules or simplifying. Complex equipment starts and stops step by step, otherwise it will cause system disorder. Just like riding a horse and driving, the reins are controlled in an orderly manner before it can move forward smoothly.
Fourth, regular maintenance. Regular inspection, cleaning, maintenance, timely detection of wear and tear, aging and other problems and treatment. Long-term use of equipment, if not repaired, small suffering into serious illness.
Fifth, safety protection. When necessary, wear protective equipment, such as hard hats, gloves, etc. Dangerous operations strictly follow safety procedures, do not take chances. Just like fishing in the abyss, if there is no protection, accidentally fall into the water, it will be too late to regret.
Sixth, keep away from children. Some products contain small parts or have dangerous functions. Do not let children touch them alone to prevent accidental ingestion and injury.
Seventh, abnormal deactivation. If there are abnormal noises, odors, smoke and other abnormalities in operation, quickly stop the machine for investigation. Do not use if it is not repaired. If the boat is on the water and the hull seeps, it must be stopped for maintenance.
Eighth, properly store. When idle, put it in a dry, ventilated and safe place to prevent damage or theft. If the sword is hidden in the sheath, protect its front and keep it safe.
