To prepare 3-amino-2-chloro-6- (trifluoromethyl) pyridine, there are several methods for its synthesis.
One method can be started from a suitable pyridine derivative. First take the pyridine with a specific substituent, and introduce the chlorine atom in a suitable position through halogenation. In this halogenation step, the appropriate halogenation reagent and reaction conditions need to be selected, so that the chlorine atom precisely falls on the target check point. Subsequently, through the amination method, the amino group is introduced into the pyridine ring with a suitable amination reagent. During the process, the reaction needs to be carefully regulated to ensure that the amination position is accurate and to avoid the occurrence of side reactions. Finally, trifluoromethyl is introduced through a specific reaction. This step may involve reagents containing trifluoromethyl, and under suitable catalyst and reaction environment, trifluoromethyl is connected to obtain 3-amino-2-chloro-6- (trifluoromethyl) pyridine.
The second method can start from different starting materials. First build the basic structure of the pyridine ring, and in the construction process, some of the required substituents are ingeniously introduced. For example, first use suitable raw materials, through condensation, cyclization and other reactions, to build a pyridine ring. When setting up, the subsequent introduction of chlorine, amino group, and trifluoromethyl can be pre-planned. After the formation of the pyridine ring, the steps of halogenation to introduce chlorine, amination to introduce amino group, and introduction of trifluoromethyl are carried out in sequence. Each step of the reaction requires fine adjustment of the reaction conditions, such as temperature, solvent, catalyst, etc., according to the characteristics of the reaction substrate, in order to achieve the best reaction effect and improve the purity and yield of the product.
Or there are other methods, such as starting with other heterocyclic compounds, through a series of functional group transformation and ring transformation. First, the heterocyclic ring is converted into a suitable intermediate by appropriate ring opening or ring expansion reaction, and then chlorine, amino group, trifluoromethyl group and other groups are gradually introduced. After multi-step reaction, the final target product is 3-amino-2-chloro-6 - (trifluoromethyl) pyridine. Each step of the reaction requires rigorous operation, and precise monitoring and control of the reaction process and products are carried out to ensure the smooth progress of the synthesis route.

I think this "3-hydroxy-2-chloro-6- (trifluoromethyl) pyridine" is a fine organic compound. Its price range in the market is difficult to determine, due to the intertwined influence of many factors.
First, the price of raw materials. The preparation of this compound requires all kinds of raw materials. If the raw materials are easy to obtain and affordable, the cost of this compound will drop, and the price will also be low. On the contrary, if the raw materials are rare and difficult to purchase, the price will be high.
Both, the preparation process. The method of preparation can be divided into complex and simple. If the process is simple and efficient, energy consumption is low, manpower is saved, and the cost is reduced; however, if the process is complex, exquisite equipment and special conditions are required, the cost will increase greatly, and the price will also rise.
The three are the supply and demand of the market. If the market demand for this product is strong, but the supply is small, the price will rise; if the demand is weak and the supply is excessive, the price will fall.
Furthermore, the level of purity also affects the price. High purity can be used in high-end fields, such as pharmaceutical research and development, electronic materials, etc., and the price is high; low purity, the use is limited, and the price is also low.
Generally speaking, in the chemical raw material market, the price of crude products may range from tens of thousands to tens of thousands per ton; if it is a high-purity high-quality product, used in fine chemicals, pharmaceutical synthesis, etc., the price per kilogram may reach hundreds or even thousands of yuan. However, this is only a rough estimate. The actual price fluctuates from time to time with changes in the market. It is necessary to observe the market conditions carefully to determine the price range.
