5-Bromo-2-(pyrrolidin-1-yl)pyridine

5 Arsenic-2 is used to fight poison with poison and evil. As mentioned in the Book of Heavenly Works, the method of using arsenic and poisonous things also has its own special effect.
Arsenic has a strong and poisonous nature. Ordinary people eat it for a while, and it will have a life. However, in the way of cultivation, there is no use for it. With it, it can cure all kinds of diseases and strange diseases, especially in the way of evil and removing the poison of cold. Those of ancient times, well aware of its nature, use it with caution, and can often achieve miraculous results.
As for the use of arsenic-1, it is the nature of taking arsenic and fighting poison with poison. The world is evil, and it is mostly produced by the condensation of poison. Its nature is surly, and it is often effective. The strength of arsenic can restrain this evil poison. Arsenic is processed according to a specific method, and it is combined with others. When applied to patients, or when subjected to treatment, it can dissipate the evil poison and balance it.
Among the people, arsenic is also often used around the house to ward off evil. Because of the evil, I am afraid of the poison of arsenic and dare not approach it. This has not yet been studied, but in the minds of the ancients, it is an important means of warding off evil.
Therefore, the use of 5% arsenic-2 (to 1-1 base) is to use the toxicity of arsenic for the purpose of treating evil and saving people. However, arsenic is actually a poisonous thing. If you use it, you must be careful about it.

If you want to make 5% mercury-2 (to the female pigeon-1 base), there are various ways to synthesize it. The preparation of the contents of "Tiangong Kaiwu" can be learned from.
In ancient recipes, if you want to get this compound, one of the methods can be extracted and aggregated from natural materials. For mercury, in mines such as Dan Sand, pure mercury can be obtained by calcining and sublimating. And female pigeon-1 base, or looking for specific herbs or mineral combinations. First take Dan Sand and place it in a closed cauldron, slowly calcined with charcoal fire, the Dan Sand is decomposed by heat, and the mercury gas rises. When cold, it condenses on the wall of the vessel. This is the main method for extracting mercury. As for the female pigeon-1 base, if it is a herbal synthesis, the corresponding herbs need to be collected, compatible according to a certain proportion, tortured with water, removed from the dregs to extract the juice, and concentrated into a paste. This is the preliminary female pigeon-1 base preparation.
Then combine mercury with the female pigeon-1 base. In ancient methods or in special pottery dishes, the female pigeon-1 base paste is first placed, and then mercury is added, and it is boiled slowly on a slow fire. During this period, it is necessary to keep stirring to fully blend the two. Because mercury is volatile, it is necessary to control the heat and duration to prevent mercury from escaping and causing the synthesis to fail.
Another method, or by chemical changes to give birth. If the female pigeon-1 base contains metal salts, it can be replaced with mercury. Take an appropriate amount of mercury and place it in a copper kettle, add the dissolved female pigeon-1 base salt solution, and then replace the mercury with metal ions to form a new compound. This is also the method of synthesizing 5% mercury-2 (to the female pigeon-1 base). However, this process requires precise measurement of the material dosage and precise preparation according to its chemical properties to obtain the best effect. In the operation room, attention should also be paid to the severity of the reaction, timely temperature control, and stable synthesis to obtain the required compound.

"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty. According to its requirements, the answer in the style of ancient text is as follows:
Mercury, also known as mercury, is a liquid metal. Its physical properties are very unique.
First of all, its form, under normal circumstances, mercury is a flowing liquid, shiny silver-white, like flowing silver, smooth and agile, difficult to touch, and flowing when tilted, unlike other things that can be shaped in one place.
Second, in terms of its density, the density of mercury is quite large, and it is heavier than ordinary things. If it is held in an utensil, it can be felt to be heavy, which is more than several times heavier than water of the same volume.
Furthermore, the melting point of mercury is very low, about minus 39 degrees Celsius. In case of a little warmth, it melts into a liquid, just like ice and snow in spring, melting and invisible. And its boiling point is not very high, about 357 degrees Celsius. When heated, it easily turns into steam and rises.
And the volatility of mercury, mercury has a certain degree of volatility. Although it is slow in the air, it can gradually evaporate and disperse around. Its vapor is colorless and odorless, but it is toxic and should not be careless.
In addition, the solubility of mercury is also specific. It is insoluble in water, mixed with water, and separated from each other, with clear boundaries. However, in some metals, mercury can form amalgam with it, which is like a blend of water and milk. This property is useful in many fields such as metallurgy.

5-Shen-2- (male-1-yl) has a certain degree of materiality. Its external appearance may take a certain shape, or be solid, and have a certain degree of materiality. This is determined by its molecular arrangement.

In terms of chemical activity, the functional groups in its molecules play an important role. The specific groups contained in the 5-Shen-2- (male-1-yl) male make it easy to reverse. It is possible that some nuclei can be produced by nuclear substitution reaction. Due to the division of the nucleus, it can attract the nucleus to attack and generate new compounds.
In the reaction of oxidants, 5-shen-2- (androgenic-1-yl) androgens also have some properties. Some atoms of their molecules, if they can be synthesized, may be synthesized under the action of appropriate oxidation or oxidation. The modification of biochemical synthesis can lead to the transformation of the whole molecule, and the transformation of other substances.
Furthermore, the acidity of 5-shen-2- (androgenic-1-yl) androgens is also one of its important properties. Whether the molecule contains soluble molecules or groups that can accept molecules depends on its acid properties. If it contains an acidic group, it can be neutralized and reversed by an acidic substance; conversely, if it has an acidic group, it can also be reacted by an acidic substance.
In addition, in the field of synthesis, 5-yen-2- (male-1-yl) males can be used in important synthesis due to their special chemical properties. By means of ingenious reverse methods, it can be used in various fields such as chemical research, materials science, etc., to achieve their unique value.

There are five baht coins today, what is the price range in the market?
I heard in "Tiangong Kaiwu": "For every ten catties of coins cast, red copper accounts for six catties, and lead (zinc) accounts for four catties. This is roughly the same." The value of money often depends on the price of copper, lead and other materials, and it is also related to the process of coinage, the amount of survival, and the rise and fall of dynasties.
In a peaceful world, when coins are well minted and abundant, the price of five baht coins may be relatively stable. If the price of copper and lead does not fluctuate greatly, an ordinary five baht coin may be easy to count, or it may be easy to cloth several inches. For example, in the Han Dynasty, the sea was flat, and five baht coins were popular all over the world. Its price is about the same.
However, in troubled times, copper and lead materials are scarce, or the coinage craftsmanship is poor, or the dynasties change, the old coins are gradually abolished, and the price of the five-baht money will change. If the war rages, copper is used for the casting of weapons, and its price is expensive, the five-baht money may also increase in value, or it may be easy to fight, or it may be easy to cloth.
Furthermore, the five-baht money has different formats. For those who are precision casters and rare, the price is higher than that of regular products. There are special commemorative coins, or the craftsmanship is outstanding, or the meaning is special, and the price is more unusual. The five-baht money can be compared, or it can be easy to have several acres of good fields, or it is easy to treasure several pieces.
Therefore, the price range of five baht money in the market is as small as the number of grains combined and the number of inches of cloth, and as many as the number of grains, the number of cloth, and even the number of treasures. It is difficult to generalize, and it depends on the many situations at that time.
