2-Iodo-5-methylthiophene is a halogenated heterocyclic compound primarily used as a key intermediate in pharmaceutical synthesis and organic electronics. It exhibits a boiling point of 81-83°C at 10 mmHg (lit.) with a density of 1.852 g/mL at 25°C and refractive index of 1.626 (n20/D). The compound should be stored under inert gas at 2-8°C, protected from light due to photosensitivity. Safety precautions include wearing acid-resistant gloves and eye protection (GHS Category IRRITANT). Its iodine substitution pattern makes it valuable for palladium-catalyzed cross-coupling reactions in material science applications.
