3-chloro-6-methyl-2-benzothiophenecarboxylic acid methyl ester - Introduction
Methyl is an organic compound with a chemical formula of C12H9ClO2S and a molecular weight of 252.72g/mol. The substance is a colorless or pale yellow liquid.
The use of the compound is mainly used as an intermediate in organic synthesis. It can be used to synthesize biologically active compounds, such as drugs, pesticides, dyes, etc. In addition, it can also be used to synthesize photosensitizers and liquid crystal materials.
the method for preparing methyl l is relatively simple, and the target product can be obtained by reacting thiophene and chlorinated methylene to generate 3-chloro-6-methylthiophene, and then reacting with dichlorocarbonate. The specific synthesis path is as follows:
1. thiophene and methylene chloride are reacted in an appropriate solvent to generate 3-chloro-6-methylthiophene.
2. React 3-chloro-6-methylthiophene with dichlorocarbonate in an alkaline medium to generate methyl.
When using or handling this compound, attention should be paid to safety. It may be irritating to the skin, eyes and respiratory system, and has some toxicity. Therefore, protective gloves, goggles and respiratory protection should be worn during operation to avoid direct contact and inhalation of its vapors. In case of accidental contact, rinse immediately with plenty of water and seek medical treatment. In addition, the substance should also be stored in a sealed container to avoid contact with oxygen, strong oxidants and strong acids to prevent accidents.
