CATO supplies 4-(((2-Oxoindolin-3-ylidene)methyl)amino)benzenesulfonamide (CAS 388626-12-8), a certified reference material (molecular formula C15H13N3O3S, MW 315.35 g/mol) for analytical method development and quality control.
4-(((2-Oxoindolin-3-ylidene)methyl)amino)benzenesulfonamide (C15H13N3O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
