CATO supplies 4-Bromo-3-(indolin-1-ylsulfonyl)benzoic acid (CAS 668261-32-3), a certified reference material (molecular formula C15H12BrNO4S, MW 382.23 g/mol) for analytical method development and quality control.
The molecular framework of 4-Bromo-3-(indolin-1-ylsulfonyl)benzoic acid (C15H12BrNO4S) is characterized by a flavonoid core, an amide group, a sulfone 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
