3-pyridinecarbonitrile, 2-amino-5-bromo-4-methyl-

What are the chemical properties of this product? I will imitate "Tiangong Kaiwu" and answer it in classical Chinese.
If this product is gold or stone, it is probably firm and stable. At room temperature, it is not easy to react with ordinary things, such as gold, "real gold is not afraid of fire refining", has extremely high chemical stability, does not melt in case of fire, does not invade with common acids and alkalis, and its quality remains unchanged.
If it is made of grass and wood, it may be easy to respond to water and gas. For example, if wood is kept in a wet place for a long time, it is easy to be infected by bacteria, because moisture can lead to the growth of bacteria and erode the fibers of wood. And exposed to sunlight and air, over time, or gradually change its color, this is because of the slow oxidation of oxygen in the air.
If it is a liquid product, if it is water, pure water, colorless and odorless, it is liquid at room temperature, and it dissolves gas when heated, and freezes when cooled. It can dissolve many substances and is an excellent solvent. It can react violently with active metals such as sodium and potassium to generate alkali and hydrogen.
If it is a mineral oil, it is more flammable. When burned, it has a strong fire and is insoluble in water, floating on water. Its chemical structure is mostly hydrocarbons, which are relatively stable. In case of extreme conditions such as strong oxidizing agents or high temperature and high pressure, it will also cause complex chemical reactions.
If it is a chemical synthesis, its chemical properties vary according to the synthetic raw materials and processes. Such as plastics, many of them have acid and alkali resistance and insulation properties. However, when heated to a certain extent, they may soften, deform or even decompose. Its chemical structure is stable, it is not easy to degrade naturally, and it can be retained in the environment for a long time.
In general, in order to determine the chemical properties of the product, it is necessary to carefully investigate its raw materials, production methods, and through various chemical experiments to clarify the characteristics, stability, solubility, and flammability of its reaction with other substances.

The main uses of this product are quite extensive. In the context of "Tiangong Kaiwu", it can be viewed from many aspects.
First, it is used for clothing, food, housing and transportation for people's livelihood. For example, fabric products can be used to make clothes to cover the body, so that people can keep warm and cover the body when the cold and heat change. "Tiangong Kaiwu" says: "All weaving fabrics, including cloud flowers, oblique texts, and elephant eyes, are all imitated by flower machines." The cloth produced is either coarse cloth for ordinary people to wear and work on a daily basis, or fine satin for rich families to make fine clothes.
Second, in the construction of buildings. Wood, masonry and other products are the cornerstones of building houses. " Wherever you build a house, you must first find the land, and choose the place where it is high and dry and free from water. "Wood is used to build roof trusses, and brick and stone barriers are used to build walls and walls, so that the residence can be sheltered from wind and rain, and provide people with a place to live.
The third is related to agricultural production. The manufacture of agricultural tools also depends on related products. Such as iron agricultural tools," Where iron is used to make tools, take the iron that has been fried and cooked. Cast iron into an anvil first, as the land where it is hammered. "Iron tools are used in agricultural activities such as plowing land, sowing, and harvesting, which greatly improves production efficiency, ensures abundant grain, and maintains people's livelihood.
Fourth, in the field of craftsmanship. After many raw materials are processed, they become exquisite handicrafts. Such as ceramic firing, "a total of one billet of labor, through seventy-two hands, a square gram becomes a tool." From clay to exquisite porcelain, it is used for daily eating utensils, or it can be used to enjoy the display, adding life interest and cultural atmosphere.
Fifth, in transportation. The manufacture of cars and boats requires all kinds of materials. "Where the body of the boat is ten feet, the mast must be two." Ships are made of wood and other materials, which are used for water transportation, carrying goods and people, promoting material exchanges and trade exchanges around the world, and promoting economic development.

The method of making the billet of this product is quite exquisite. The ancient good workmanship, when making the billet, the first material is selected. You must look for materials with fine texture and fine texture. This is the foundation of making the billet. If the material is not good, it will be difficult to make the billet into a high-quality product.
After choosing good materials, it will enter the cutting process. The craftsman transports exquisite tools, and cuts them precisely according to the size planned in advance. The cutting line is as straight as an ink rope, not less than a millimeter. This is not a skill that has been honed for many years, and it cannot be done.
Then it is carved. The workmanship of carving is especially ingenious. The craftsman uses the knife as a pen to outline the shape on the billet. Whether it is a smart auspicious beast, or a graceful flower, it is all lifelike. Every knife is engraved, full of craftsman's thinking, priorities, and laws.
And in the process of making billets, the flatness and symmetry of the billets are also very important. Craftsmen often use leveling tools and rulers to measure repeatedly. If there is a slight deviation, it will be corrected in time. Make sure that the billets are regular, without unevenness, and without loss of deflection.
When the general shape is first formed, it needs to be polished finely. With sand and gravel of different thicknesses, from coarse to fine, polished layer by layer. Make the surface of the billet smooth like a mirror and feel warm to the touch. This polishing effort is time-consuming and laborious, but it can improve the quality of the billets to a higher level.
All these steps are interconnected and indispensable. The craftsmen use their dedication and exquisite skills to make high-quality blanks, laying a solid foundation for the success of subsequent utensils.

Nowadays, there is a thing that has a different price in the market. Or the price varies from time to time, place, and quality, and it is difficult to determine a certain number.
I have heard the people of various cities say that in prosperous cities, if the quality is excellent, the price may be high, up to a thousand gold; in remote places, if the quality is slightly inferior, the price may only be a hundred gold. And the abundance of time and changes in supply and demand can all affect its price.
If the year is abundant and the supply exceeds the demand, the price will be cheap; if the year is poor, and the goods are rare and in demand, the price will surge.
And because the material is different, the price will also be hanging. Those who are fine are like beautiful jade, and the materials are all good, and their price is expensive; those who are coarse are of simple stone quality, and the price is low.
Therefore, if you want to know the price of this thing in the market, you should carefully observe its seasonal changes, regional differences, and material differences. In a rich year, in a rich land, those with excellent materials may cost between five hundred gold and a thousand gold; in a poor year, in a remote soil, those with poor materials may cost less than a hundred gold. It is difficult to generalize, but all factors must be taken into account to obtain its approximate price.

The safety precautions related to a certain product are related to the personal safety of the user and the normal operation of the product, which should not be underestimated. Today, it is discussed in the style of the ancient classical saying of "Tiangong Kaiwu".
First, observe the environment in which the product is located. If the place is placed, it must be dry and non-humid to prevent water vapor from invading and damaging the internal components. If it is in a humid place, it is like a wood soaked in water, and it will rot for a long time. And the ambient temperature also needs to be suitable. It is not suitable for extreme heat and cold. Extreme heat such as hot summer sun exposure to gold, and severe cold like cold ice wrapped in iron in midwinter can degrade the performance of the product.
Second, be sure to follow the guidelines when using it. Before operation, read the instructions carefully to understand the functions and steps. Don't speculate on your own, If the boat is running in water, the unknown channel and the method of controlling the boat will inevitably lead to the risk of overturning. During the operation, the action should be stable and accurate, and do not be impatient. If you are in a hurry, mistakes will often occur.
Third, product maintenance cannot be ignored. Regular cleaning, dust removal and filth removal, such as a person's bath, the body is clean and refreshed, and the product is the same, clean can run smoothly. Components are worn and replaced in time, like the axles of the car. If they are worn too much, the car will be unstable, and so will the product parts. If they run with disease, hidden dangers will abound.
Fourth, use electricity and treat it with caution. Use a suitable power supply and do not replace it at will to avoid voltage discrepancies and burn components. Plug in and unplug the power supply, turn off the equipment first, such as cutting off the current and closing the gate, in an orderly manner, to ensure safety.
All these are essential for product safety. Users should keep in mind and follow the regulations to ensure long-term stability and worry-free use of the product.
