Pyridine, 3-azido-2-chloro-

This is a question about the chemical properties of amino-containing substances. Amino-containing substances have various properties and unique chemical behaviors.
First, amino groups are alkaline. Because nitrogen atoms have lone pairs of electrons and can accept protons, they can react with acids to form corresponding salts. For example, taking methylamine as an example, when it meets hydrochloric acid, methylamine hydrochloride will be formed. This is a typical reaction of acid-base neutralization, and the alkalinity of amino groups is revealed here.
Second, it can participate in nucleophilic substitution reactions. The nitrogen atom of the amino group has nucleophilic properties due to its lone pair of electrons, which can attack electrophilic reagents. For example, in the reaction of halogenated hydrocarbons, amino groups can replace halogen atoms to form new compounds. For example, when bromoethane reacts with ammonia, the amino group in ammonia will replace the bromine atom of bromoethane to produce ethylamine and hydrogen bromide.
Third, a condensation reaction can occur. The common one is condensation with carboxyl groups to form peptide bonds. In organisms, amino acids are connected to form peptides and even proteins through this condensation reaction, which is a key process of life activities. When two molecules of amino acids meet, the amino group of one molecule dehydrates and condensates with the carboxyl group of another molecule to form a peptide bond and generate a molecule of water at the same time.
Fourth, an oxidation reaction can be carried out. However, the oxidation reaction of amino groups is more complicated, with different reaction conditions and different products. Under the action of certain oxidants, amino groups may be oxidized to nitro or nitroso and other nitrogen-containing functional groups.
In summary, the chemical properties of amino-containing substances are rich and diverse, and they play an important role in many fields such as organic synthesis and biochemistry, and have far-reaching effects on many chemical reactions and life processes.

In the era of "Tiangong Kaiwu", although there was no such detailed explanation, in today's understanding of the chemical industry, cyanyl groups have a wide range of uses.
Cyanyl groups are used in organic synthesis, which can be described as the key. Cover because it can introduce special functional groups, so that organic molecules have different properties and reactivity. Such as the preparation of nitriles, the nitriles can be hydrolyzed to obtain carboxylic acids, or reduced to amines. This is essential for the creation of medicine and pesticides. In terms of medicine, the construction of many drug molecules involves cyanyl groups, which allows the precise combination of drugs and targets to exert therapeutic effects.
Furthermore, in the field of materials, cyanyl groups also have their uses. Some polymers containing cyanide groups have excellent heat resistance and chemical corrosion resistance. These materials can be used to make high-end engineering plastics, which are used in aerospace, electronic equipment and other places where material properties are strictly required. The parts of aerospace vehicles need to be able to withstand extreme temperature changes and chemical attack, and cyanide-containing polymers are just right.
As for cyanide-oriented, it is used in organic synthesis strategies to guide chemists. Cyanyl groups can be used as positioning groups to guide reactions to occur at specific locations, improving the selectivity and efficiency of reactions. In this way, chemists can precisely construct complex organic molecular structures according to the design, which is of great significance in the field of total synthesis of natural products. Natural products have complex structures and high synthesis difficulty. Cyanyl guidance can help chemists overcome difficulties and achieve the synthesis of target molecules, providing a material basis for new drug research and development, biological activity research, etc.
Most importantly, cyanide groups and their guidance are key elements in many fields such as chemical industry, medicine, and materials, promoting the development of various industries and having far-reaching impact.

There are many ways to synthesize substances containing amino and cyanyl groups.
First, the synthesis of ammonia cyanide. Ammonia and cyanide are used as raw materials, and under specific conditions, the two interact to form compounds containing amino cyanide. For example, when ammonia and hydrogen cyanide are present at appropriate temperatures, pressures and catalysts, they can react to form amino cyanide. This reaction process is relatively direct, but it is necessary to pay attention to the precise control of the reaction conditions. Due to the toxicity of hydrogen cyanide, proper protective measures should be taken during operation.
Second, the synthesis of halogenated hydrocarbons by cyanide by aminolysis. First, halogenated hydrocarbons react with cyanide to form nitriles, and then nitriles react with ammonia to introduce amino groups through aminolysis. If a halogenated alkane is reacted with sodium cyanide in a suitable solvent to obtain an alkyl nitrile, and the alkyl nitrile is reacted with ammonia under the action of a catalyst to obtain an aminocyanyl-containing product. There are a few more steps in this path, but the raw materials are relatively common and easy to obtain.
Third, the synthesis of aldosterone and ketone with ammonia and hydrocyanic acid. Aldosterone or ketone is first added to hydrocyanic acid to generate cyanoalcohol, which is then reacted with ammonia, and the target product is obtained through a series of conversions. Taking formaldehyde as an example, formaldehyde is added with hydrocyanic acid to obtain hydroxyacetonitrile, and hydroxyacetonitrile is then reacted with ammonia to obtain a compound containing aminocyanate. In this process, the use of hydrocyanic acid still needs to be cautious, and the regulation of reaction conditions is related to the yield and purity of the product.
Fourth, the stepwise construction method of organic synthesis reagents. Using reagents such as azide, nitrogen-containing groups are first introduced, and then converted to amino groups, while cyanide groups are introduced through other reactions. This method is more flexible and can be designed according to the specific structure of the target product, but the reaction steps are more complicated and require high synthesis technology.

For those containing nitrogen groups, many matters must be paid attention to during storage and transportation.
The first to bear the brunt is the environmental conditions. Nitrogen-containing substances are mostly sensitive to temperature and humidity. High temperature can easily cause changes in their chemical properties, or cause adverse reactions such as decomposition. Therefore, the storage place should be selected in a cool place, and the humidity should also be moderately controlled to prevent deliquescence due to high humidity, or changes in their properties due to low humidity.
Furthermore, isolation from other substances is also crucial. Nitrogen-containing substances tend to have higher chemical activity and are prone to react with many substances. Such as strong oxidizing agents, reducing agents, etc., should be stored and transported separately to avoid accidental chemical reactions and endanger safety. If mixed with oxidizing agents, or due to violent reactions, there is a risk of heat, fire or even explosion.
The choice of packaging should not be underestimated. Strong and well-sealed packaging materials are required to prevent the leakage of nitrogen-containing substances. The packaging should not only be able to resist external impact and avoid damage, but also have good chemical stability and do not react with the contained substances. At the same time, warning labels should be clearly marked on the packaging to make the contact clear about its characteristics and potential hazards.
During transportation, the smooth driving should not be ignored. Avoid excessive bumps and vibrations to prevent damage to the packaging and leakage of substances. And the internal environment of the transport vehicle also needs to be maintained stable, without large fluctuations in temperature and humidity.
As for substances containing amino groups, in addition to the above common points, due to their alkalinity, care should also be taken to avoid contact with acidic substances. When the two meet, they are prone to neutralization reactions, which not only change the original properties of the substance, but also may produce harmful products.
In summary, nitrogen-containing and amino-containing substances need to be treated with caution in terms of environment, isolation, packaging and transportation conditions during storage and transportation to ensure safety and stability of material properties.

The price of amino-containing substances in the commercial market varies depending on the purity of the quality, the amount of the amount, and the wide and narrow use. In today's words, those that contain two amino groups and have cyanide orientation are difficult to determine, but they can be deduced slightly.
Such substances are mostly related to chemical and pharmaceutical matters. If they are pure in quality and widely used in industry, the price may be higher. Looking at the chemical raw materials in various cities, those with excellent quality and diverse uses, the price per amount is often above 100 gold, and even up to 1000 gold. If the materials containing amino groups and have cyanide orientation are involved in the synthesis of fine chemicals and drugs, their preparation may be difficult, and the demand or cutting, the price should be very high.
However, there are also differences. If the mass production is quite abundant, the supply is sufficient, and the price may be slightly lower. In the chemical industry, those who grow on a large scale can often reduce the cost, and the price will fall. And if the quality varies, the use is limited, and the price cannot be high.
Roughly speaking, the price of such goods in the market is between tens of gold and hundreds of gold per kilogram or in the range of tens of gold. This is the number of ideas, and the actual price depends on the supply and demand of the market, the cost of production, and the cost of transportation. Therefore, if you want to know the exact price, you must carefully study the market situation and consult the industry.
