Methyl 5-methoxy-3-methylbenzo[b]thiophene-2-carboxylate CAS 75416-70-5

Description

The occurrence of Methyl 5-methoxy-3-methylbenzo[b]thiophene-2-carboxylate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Methyl 5-methoxy-3-methylbenzo[b]thiophene-2-carboxylate (CAS 75416-70-5), molecular formula C12H12O3S and molecular weight 236.29 g/mol, is a CATO reference standard with documented purity and traceability.

Methyl 5-methoxy-3-methylbenzo[b]thiophene-2-carboxylate (C12H12O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
