There are several common methods for the synthesis of 3-amino-2-chloro-6-methylpyridine.
First, 2-chloro-6-methylpyridine is used as the starting material. Shilling 2-chloro-6-methylpyridine and appropriate nitrifying reagents, such as mixed acid of concentrated nitric acid and concentrated sulfuric acid, carry out nitrification reaction at specific temperature and reaction conditions to obtain 2-chloro-3-nitro-6-methylpyridine. This process requires attention to the proportion of mixed acid and precise control of reaction temperature to prevent side reactions from occurring. Then, the obtained 2-chloro-3-nitro-6-methylpyridine is reduced with a suitable reducing agent, such as iron powder and hydrochloric acid, or hydrogen under the action of palladium carbon catalyst, so that the nitro group is converted into an amino group, so as to obtain 3-amino-2-chloro-6-methylpyridine. When reducing iron powder with hydrochloric acid, attention should be paid to the pH and reaction time of the reaction system; in principle, hydrogen pressure, catalyst dosage and other factors should be paid attention to.
Second, you can start from 2,3-dichloro-6-methylpyridine. Let 2,3-dichloro-6-methylpyridine react with ammonia gas at high temperature and pressure and in the presence of a suitable catalyst. In this reaction, the pressure of ammonia gas, the reaction temperature and the activity of the catalyst have a great influence on the reaction process and product yield. Ammonia attacks the chlorine atom on 2,3-dichloro-6-methylpyridine to achieve the substitution of chlorine by amino groups, and then generates the target product 3-amino-2-chloro-6-methylpyridine.
Third, 6-methyl-2-pyridine is used as the starting material. First, 6-methyl-2-pyridinone is chlorinated, and appropriate chlorination reagents, such as phosphorus oxychloride, are selected. Under suitable conditions, the hydroxyl group is converted into chlorine atoms to obtain 2-chloro-6-methyl pyridine. After that, 3-amino-2-chloro-6-methyl pyridine can be synthesized according to the nitration and reduction steps described above. This route needs to pay attention to the control of chlorination conditions to avoid side reactions such as excessive chlorination.
Each synthesis method has its own advantages and disadvantages. The appropriate synthesis path should be carefully selected according to actual needs, such as raw material availability, cost, product purity requirements and other factors.

3-Amino-2-chloro-6-methylpyridine is one of the organic compounds. Its physical properties are unique, let me tell them one by one.
Looking at its appearance, it is often in the form of a white-like to light yellow crystalline powder, delicate and uniform, with a bright color, which is visually available.
As for the melting point, it is about 135 ° C - 139 ° C. When the temperature gradually rises, the compound slowly melts from solid to liquid, and the temperature range of this transition is relatively stable, which can be an important basis for identification and purification. < Br >
In terms of solubility, it shows a certain solubility in organic solvents, such as methanol, ethanol, dichloromethane, etc. Methanol and ethanol, with their polar characteristics, can form a moderate interaction with 3-amino-2-chloro-6-methylpyridine to dissolve them. Although dichloromethane has a weak polarity, it can also disperse the compound to a certain extent due to its special molecular structure. In water, its solubility is relatively limited, which is due to the difference between the polarity of water and the molecular structure of the compound.
In addition, 3-amino-2-chloro-6-methylpyridine is chemically stable at room temperature and pressure. When it encounters strong acids, bases or strong oxidants, its molecular structure may change due to chemical reactions. The balance of stability and reactivity is of great significance in many fields such as organic synthesis. Its stability ensures the safety of storage and transportation, and appropriate reactivity provides the possibility for it to participate in various organic reactions.

3-Amino-2-chloro-6-methylpyridine, the market price of this product often changes due to various reasons. In the past, in the world of Tiangong Kaiwu, although there was no such precise chemical, the price of various process materials was also affected by the origin, supply and demand. Today's 3-amino-2-chloro-6-methylpyridine has different origins and different prices. If it is produced in a place rich in resources and well-crafted, the cost may drop, and the price will also decrease.
Furthermore, the state of supply and demand has a deep impact on the price. If there are many people in the market, such as the pharmaceutical and chemical fields, the demand for it surges, and the supply exceeds the demand, the price will rise; on the contrary, if the supply exceeds the demand, the manufacturer will sell its goods, or reduce the price in order to sell.
The simplicity of the production process and the new and old technology are also related to the cost and price. New and clever methods may reduce consumption and improve production, resulting in lower costs and better prices; the old method is cumbersome and the cost is high, and the price follows.
The market situation in the city changes rapidly, and its price may fluctuate between tens of yuan and hundreds of yuan per kilogram. It is difficult to determine the value. Buyers should carefully observe market dynamics and compare prices from multiple parties to obtain a suitable price and seek business benefits.

3-Amino-2-chloro-6-methylpyridine, when storing and transporting, you need to pay attention to many matters. This is an organic compound with unique properties. If you are not careful, it will cause disaster.
Let's talk about storage first. First, you must find a cool, dry and well-ventilated place. Because the material is susceptible to change when heated, if it is in a warm and humid place, it may cause damage to the quality or even cause dangerous reactions. Second, it needs to be stored in isolation from oxidants, acids, etc. This is because of its active chemical properties. It encounters oxidants or causes severe oxidation reactions. It may also react in complex reactions when exposed to acids, which endangers safety. Third, the storage container must be tightly closed. In order to prevent it from evaporating in the air, the first is to pollute the environment, and the second is that if the concentration reaches a certain level, there may be a risk of explosion. And the container should be checked regularly to see if it has any leakage.
As for the time of transportation, there are also important points. The transportation vehicle is selected to be suitable and has corresponding safety protection facilities. Loading must be safe to prevent package damage caused by bumps and collisions. During transportation, drivers and escorts should pay close attention and not leave their posts without authorization. In case of bad weather, such as heavy rain, high temperature, etc., they should be more cautious. If necessary, suspend transportation and seek safe places to avoid. And the transportation route planning should also be careful to avoid crowded areas and environmentally sensitive places to reduce the harm in case of an accident. Therefore, the safety of 3-amino-2-chloro-6-methylpyridine during storage and transportation is guaranteed.
