3-Methyl-7-chlorobenzo[b]thiophene is a key heterocyclic intermediate primarily used in pharmaceutical synthesis, notably as a precursor for the antifungal drug Sertaconazole Nitrate. The compound exhibits a boiling point of 280.5±20.0°C (predicted) and density of 1.293 g/cm³ at 20°C. With a logP value of 4.19, it demonstrates good lipid solubility. Storage recommendations include protection from light at 2-8°C. Safety precautions should be observed as it may cause skin/eye irritation (GHS Category 2). Its unique benzo[b]thiophene structure with methyl and chloro substitutions makes it valuable for constructing bioactive molecules.
