67808-64-4 - Introduction
Acid methyl ester is an organic compound with the chemical formula C9H7NO3S. It has the following properties:
-Appearance: acid methyl ester exists in the form of white crystals or powder.
-Solubility: It has good solubility in common organic solvents, such as ethanol, chloroform and dimethylformamide.
-Stability: acid methyl ester is relatively stable under normal conditions, but light and strong oxidants should be avoided.
acid methyl ester is commonly used in material research and drug development in the field of organic synthesis. Its main uses include:
-Organic optoelectronic materials: It can be used to synthesize polymers containing thiophene groups, and is widely used in organic solar cells, organic field effect transistors, organic light-emitting diodes and other devices.
-Drug development: acid methyl ester and its derivatives show certain biological activity, so they are often used as intermediates or starting materials in the drug development process.
The method of preparing an acid methyl ester usually involves the following steps:
1. Condensation of 5-carboxylic acid-2-thiophene with hydrofluoric acid to obtain 5-methylthiothiophene-2-carboxylic acid.
2. 5-Methylthiothiophene-2-carboxylic acid is oxidized in the presence of an oxidizing agent to obtain 5-formylthiothiophene-2-carboxylic acid.
3. Esterify 5-formylthiothiophene-2-formic acid to obtain the final product acid methyl ester.
Regarding safety information, acid methyl ester is a chemical reagent for laboratory use and should comply with relevant safety procedures. It may cause irritation to the eyes, skin and respiratory tract, so wear appropriate personal protective equipment, such as laboratory gloves, protective glasses and respiratory protection equipment. During storage and handling, avoid contact with oxidants, acids or strong bases, and keep away from fire sources. Read and understand the relevant safety data sheets and operating instructions before use.
