2-Thiophenecarbonyl Chloride (CAS 1079-85-6) is a key heterocyclic acylating agent. Its molecular formula is C5H3ClOS. This reagent is industrially synthesized via chlorination of 2-thiophenecarboxylic acid, serving as a vital intermediate for constructing complex thiophene-based scaffolds in pharmaceutical and agrochemical synthesis.
Strictly store under anhydrous conditions at low temperatures to prevent hydrolysis. Use appropriate PPE due to severe corrosivity and lachrymatory properties. Avoid direct contact with skin and eyes; ensure adequate ventilation during handling.
