3-アミノベンゼンスルホンアミド

使用3-Aminobenzenesulfonamide serves as a precursor for synthesizing 1-substituted-3-(3-aminosulfonylphenyl)thioureas by reacting with freshly prepared aroyl or heteroaryl isothiocyanates in dry acetonitrile[1]. It is also used to prepare pyridinium derivatives through reaction with pyrylium salts and acetic anhydride[2]. In membrane fabrication, 3-aminobenzenesulfonamide acts as a monoamine monomer introduced into interfacial polymerization, where it competes with polyethyleneimine for trimesoyl chloride reaction sites to produce positively charged nanofiltration membranes[3].
