189807-21-4 - Introduction
Nature:
4-fluoro-2-(trifluoromethyl)benzoyl chloride is a colorless liquid with a pungent odor. It has a high melting point and boiling point, and can be dissolved in a variety of organic solvents such as ethanol and chloroform. This compound is a powerful acylating agent and can react with alcohols, amines and acids to give the corresponding esters, amides and acid derivatives.
Use:
4-fluoro-2-(trifluoromethyl)benzoyl chloride has a wide range of applications in the field of organic synthesis. It is usually used as a reagent for the acyl chloride reaction in organic synthesis. The acyl chloride reaction is a type of reaction commonly used in organic synthesis, which is used to introduce acyl groups (functional groups with acyl groups) into molecules to build complex organic compounds.
Method:
4-fluoro-2-(trifluoromethyl)benzoyl chloride can be prepared by the reaction of 2-(trifluoromethyl) benzoic acid and thionyl chloride under certain temperature conditions. The reaction is usually carried out under an inert atmosphere to prevent reaction with water and oxygen in the air.
Safety Information:
4-fluoro-2-(trifluoromethyl)benzoyl chloride is an irritating compound and care should be taken to avoid contact with the skin, eyes, and respiratory tract. Appropriate personal protective equipment such as gloves, goggles and respiratory protection equipment should be used during operation.
