3-Methyl-5-chlorobenzothiophene is a halogenated benzothiophene derivative widely used as a key intermediate in pharmaceutical synthesis, particularly for developing kinase inhibitors and antimicrobial agents. This compound exhibits a melting point of 33-36°C and boiling point of 144°C at 14 mmHg, with a density of 1.293 g/cm³. Its unique structure combines electron-rich thiophene and electron-withdrawing chloro groups, making it valuable for constructing bioactive molecules. The material should be stored in sealed containers at room temperature, protected from light. Safety precautions include wearing protective gloves due to potential skin irritation (GHS Category 2).
