Nonafluorobutanesulfonyl fluoride (CAS: 13948-25-7) is a highly fluorinated sulfonylating agent. Synthesized via electrophilic fluorination of butanesulfonyl precursors, it features the molecular formula C4F9SO2F. This reagent is critical for introducing perfluorobutylsulfonyl groups into organic frameworks.
Strictly store in sealed, dry containers under inert atmosphere at controlled temperatures. Use full PPE including acid-resistant gloves due to severe corrosivity and hydrolysis risks releasing HF gas. Avoid inhalation or skin contact.
