There are many different methods for the synthesis of Ethyl 3-chloro-6- (trifluoromethyl) pyridine-2-carboxylate. The common one is to use pyridine containing the corresponding substituent as the starting material. First take the pyridine derivative, which, under suitable reaction conditions, interacts with the halogenating reagent to introduce the chlorine atom at a specific position. The halogenating reagent used, or thionyl chloride, phosphorus oxychloride, etc. In this reaction, it is necessary to pay attention to the reaction temperature, time and reagent dosage, so that the chlorine atom can be precisely replaced to obtain the chlorine-containing pyridine intermediate.
After that, the intermediate reacts with the reagent containing trifluoromethyl to introduce the trifluoromethyl. In this step, suitable nucleophilic substitution reaction conditions can be selected, and trifluoromethyl-containing reagents are used, such as Grignard reagents such as trifluoromethyl halide magnesium, or other reagents that can effectively provide trifluoromethyl. In the reaction, the choice of solvent is very critical, and organic solvents such as anhydrous ether and tetrahydrofuran are commonly used to ensure the smooth progress of the reaction.
Finally, the resulting chlorine and trifluoromethyl-containing pyridine derivatives are reacted with ethanol and appropriate esterification reagents to achieve carboxylate esterification, thereby obtaining Ethyl 3-chloro-6 - (trifluoromethyl) pyridine-2 - carboxylate. In the esterification reaction, concentrated sulfuric acid is used as a catalyst to reflux at a suitable temperature, and the reaction is also assisted by condensing agents such as dicyclohexyl carbodiimide (DCC). The reaction conditions need to be optimized according to the actual situation to improve the yield and purity of the product. In this way, the target product can be obtained after several steps of reaction.

Ethyl 3 - chloro - 6 - (trifluoromethyl) pyridine - 2 - carboxylate is an organic compound. Its physicochemical properties are as follows:
From the point of view, this substance is usually in a liquid or crystalline state, colored or colorless, or with some color, but its exact appearance often varies depending on the purity and preparation method.
When it comes to the melting point, its molecular structure contains special functional groups, such as chlorine atoms, trifluoromethyl groups and ester groups, which cause unique intermolecular forces. Usually the melting boiling point has a certain range, but the exact value must be determined accurately according to the experiment. The presence of ester groups makes its boiling point or due to intermolecular dipole-dipole forces increase. < Br >
In terms of solubility, it has good solubility in organic solvents such as dichloromethane, chloroform, acetone, and ethanol. This is because organic solvents can form interactions such as van der Waals forces and hydrogen bonds with the compound. However, in water, due to its non-extremely high molecular polarity and the hydrophobicity of trifluoromethyl, its solubility is limited.
In terms of stability, it is still stable under conventional conditions. In case of strong acids, strong bases, or extreme conditions such as high temperature and light, chemical reactions can occur. In case of strong bases, ester groups can be hydrolyzed to form corresponding carboxylic salts and alcohols; in case of strong acids, reactions on pyridine rings may be initiated. In addition, its density is also one of the important physical and chemical properties, due to the relative atomic mass and molecular structure arrangement of each atom, the density has a specific value, which is quite useful in practical applications such as separation and purification.

I don't know the price range of "Ethyl 3-chloro-6- (trifluoromethyl) pyridine-2-carboxylate" in the market. This is a fine chemical, and its price often varies depending on quality, purity, supply and demand, and purchase quantity.
If you want to find the price, you can go to the chemical product trading platform, supplier website. Or contact chemical raw material suppliers and distributors to inquire about their quotations.
