Description
1-Amino-2-(4-chlorophenylazo)naphthalene-5-sulfonamide 118876-55-4 5-Amino-6-[(4-chlorophenyl)azo]-1-naphthalenesulfonamide 5-Amino-6-[2-(4-chlorophenyl)diazenyl]-1-naphthalenesulfonamide (C16H13ClN4O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
