Chemical Structure
Description
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 368-43-4 Phenylsulfonylfluoride Benzenesulfonyl fluoride Benzenesulphonyl fluoride 4-11-00-00049 (Beilstein Handbook Reference) BRN 2206835 EINECS 206-707-2 NSC 8543 Phenylsulfonyl fluoride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 166.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
