Methyl C3-sulfonyl amino methyl acetate C2-thiophene carboxylate - Introduction
Methyl 3-sulfonylaminoacetic acid methyl ester-2-thiophenecarboxylate is commonly referred to as STM, which is an organic compound. The following is a detailed description of the nature, use, formulation and safety information of STM:
Nature:
- STM is a colorless or light yellow liquid with a pungent odor.
-It is almost insoluble in water at room temperature, but soluble in organic solvents such as ethanol and dimethylformamide.
- STM is a highly reactive compound that may burn or explode.
Use:
- STM is usually used as a reagent in organic synthesis reactions, such as acting as a catalyst in certain carbon-carbon coupling reactions.
-It can also be used as an intermediate of organic electronic materials for the preparation of organic solar cells, organic field effect transistors, etc.
Preparation Method:
-The preparation method of STM is complicated and generally involves a multi-step reaction.
-A common preparation method is to react methyl 2-thiophenecarboxylate with thionyl chloride to obtain methyl 3-sulfonyl-2-thiophenecarboxylate.
-Then the obtained 3-sulfonyl-2-thiophenecarboxylic acid methyl ester is reacted with methanol to obtain the final 3-sulfonylaminoacetic acid methyl ester-2-thiophenecarboxylic acid methyl ester.
Safety Information:
- STM is a toxic compound that is irritating and corrosive.
-Wear appropriate protective equipment such as chemical gloves, goggles and protective clothing when handling and operating STMs.
-Avoid contact with skin and inhalation of its vapor, and ensure that it is operated in a well-ventilated place.
-When storing and handling STMs, keep them away from ignition and combustibles.
