Chemical Structure
Description
N-(2-(1H-indol-3-yl)ethyl)-4-chloro-3-nitrobenzenesulfonamide (CAS 880139-18-4), molecular formula C16H14ClN3O4S and molecular weight 379.82 g/mol, is a CATO reference standard with documented purity and traceability.
N-(2-(1H-indol-3-yl)ethyl)-4-chloro-3-nitrobenzenesulfonamide (C16H14ClN3O4S) contains a flavonoid core, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
