Chemical Structure
Description
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, 4-Bromo-N-((5-((3-chlorobenzyl)thio)-4-methyl-4H-1,2,4-triazol-3-yl)methyl)benzenesulfonamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 487.82 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 4-Bromo-N-((5-((3-chlorobenzyl)thio)-4-methyl-4H-1,2,4-triazol-3-yl)methyl)benzenesulfonamide (CAS 338421-63-9), a certified reference material (molecular formula C17H16BrClN4O2S2, MW 487.82 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
