CAS 59337-92-7: Methyl 3-(chlorosulfonyl)-2-thiophenecarboxylate

Description: Methyl 3-(chlorosulfonyl)-2-thiophenecarboxylate is a chemical compound characterized by its unique functional groups and structure. It features a thiophene ring, which is a five-membered aromatic heterocycle containing sulfur, contributing to its reactivity and potential applications in organic synthesis. The presence of a chlorosulfonyl group (-SO2Cl) enhances its electrophilic properties, making it a useful intermediate in the synthesis of various sulfonamide compounds and other derivatives. The methyl ester group (-COOCH3) provides additional reactivity, allowing for further functionalization. This compound is typically a colorless to pale yellow liquid or solid, depending on its purity and form. It is important to handle it with care due to its potential reactivity and the presence of chlorine, which can pose health risks. Methyl 3-(chlorosulfonyl)-2-thiophenecarboxylate is utilized in pharmaceutical and agrochemical research, where it serves as a building block for more complex molecules. Proper safety measures should be observed when working with this compound, including the use of personal protective equipment and working in a well-ventilated area.
