2-Acetylbenzo[b]thiophene is an important heterocyclic compound widely used as a pharmaceutical intermediate, notably in the synthesis of zileuton (as impurity standard) and other bioactive molecules. It features a melting point of 86-88°C and boiling point of 304.5±15.0°C at 760 mmHg. The compound has a density of 1.219 g/cm³ and is soluble in organic solvents like chloroform and ethyl acetate. Storage should be in sealed containers at room temperature, protected from light. Safety precautions include wearing protective equipment due to potential irritation (GHS Category 2). Its unique structure combining acetyl and benzothiophene moieties makes it valuable for medicinal chemistry research.
