701-34-8 4-Bromobenzenesulfonamide Benzenesulfonamide, p-bromo- Benzenesulfonamide, 4-bromo- (9CI) 3-11-00-00104 (Beilstein Handbook Reference) AI3-00699 BRN 2691657 p-Bromobenzenesulfonamide NSC 31049 CAS 701-34-8 chemical structure

Description

The molecular framework of 701-34-8 4-Bromobenzenesulfonamide Benzenesulfonamide, p-bromo- Benzenesulfonamide, 4-bromo- (9CI) 3-11-00-00104 (Beilstein Handbook Reference) AI3-00699 BRN 2691657 p-Bromobenzenesulfonamide NSC 31049 (C6H12BrNO2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
