2-Bromo-3-methylthiophene is a halogenated heterocyclic compound widely used as a key intermediate in pharmaceutical and agrochemical synthesis. It features a boiling point of 173-176°C (lit.) and density of 1.572 g/mL at 25°C. The compound exhibits a refractive index of 1.572 (n20/D) and flash point of 68°C. As a versatile building block, it participates in cross-coupling reactions and serves as a precursor for various thiophene derivatives. Storage should be in sealed containers at 2-8°C under inert atmosphere. Safety precautions include wearing protective gloves/eyewear due to its irritating properties (GHS Category 2).
