2-Iodothiophene is an important halogenated heterocyclic compound widely used in organic synthesis, particularly as a key intermediate for pharmaceuticals and organic electronic materials. This compound has a boiling point of 73°C at 2.0 kPa (15 mmHg) and density of 1.902 g/mL at 25°C (lit.). The refractive index is 1.651 (n20/D). As a reactive building block, it participates in various cross-coupling reactions (e.g., Suzuki, Stille). Storage requires protection from light at 2-8°C under inert atmosphere. Safety precautions include wearing gloves/eye protection due to potential skin/eye irritation (GHS Category 2). The copper-stabilized form prevents undesired polymerization.
