Chemical Structure
Description
4-(tert-Butyl)-N-(5-chloro-2-(1H-1,2,4-triazol-1-yl)phenyl)benzenesulfonamide (CAS 868269-06-1) is a high-purity analytical reference standard with the molecular formula C18H19ClN4O2S and a molecular weight of 390.89 g/mol.
4-(tert-Butyl)-N-(5-chloro-2-(1H-1,2,4-triazol-1-yl)phenyl)benzenesulfonamide (C18H19ClN4O2S) contains a steroid 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.
