4-(Trifluoromethylsulfonyl)benzonitrile (CAS: 127608-59-9, Formula: C8H4F3NO2S) is a high-purity electrophilic intermediate synthesized via sulfonation of benzonitrile derivatives. It serves as a critical building block for introducing trifluoromethylsulfonyl groups into complex scaffolds.
Store in airtight containers under inert atmosphere at 2-8°C. Use appropriate PPE to prevent skin contact and inhalation; avoid exposure to strong bases which may cause decomposition.
