Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Bromo-N-{[4-methyl-5-({[4-(trifluoromethyl)phenyl]methyl}sulfanyl)-4H-1,2,4-triazol-3-yl]methyl}benzene-1-sulfonamide.
CATO supplies 4-Bromo-N-{[4-methyl-5-({[4-(trifluoromethyl)phenyl]methyl}sulfanyl)-4H-1,2,4-triazol-3-yl]methyl}benzene-1-sulfonamide (CAS 338421-64-0), a certified reference material (molecular formula C18H16BrF3N4O2S2, MW 521.37 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, 4-Bromo-N-{[4-methyl-5-({[4-(trifluoromethyl)phenyl]methyl}sulfanyl)-4H-1,2,4-triazol-3-yl]methyl}benzene-1-sulfonamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 521.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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.
CATO manufactures 4-Bromo-N-{[4-methyl-5-({[4-(trifluoromethyl)phenyl]methyl}sulfanyl)-4H-1,2,4-triazol-3-yl]methyl}benzene-1-sulfonamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
