5-(2-Pyridyl)thiophene-2-sulfonyl chloride (CAS 100768-46-9, C9H6ClNO2S2) is a heterocyclic sulfonylating agent synthesized via chlorosulfonation of 5-(2-pyridyl)thiophene. This reagent serves as a critical intermediate for constructing sulfonamide derivatives in medicinal chemistry.
Strictly store under inert atmosphere at 2-8°C to prevent hydrolysis. Personnel must wear full PPE including acid-resistant gloves due to severe skin corrosion risks upon contact with moisture.
