CATO supplies N-(4-Bromo-2-methylphenyl)-2-((5-(4-chlorophenyl)-4-(p-tolyl)-4H-1,2,4-triazol-3-yl)thio)acetamide (CAS 476485-93-5), a certified reference material (molecular formula C24H20BrClN4OS, MW 527.86 g/mol) for analytical method development and quality control.
The molecular framework of N-(4-Bromo-2-methylphenyl)-2-((5-(4-chlorophenyl)-4-(p-tolyl)-4H-1,2,4-triazol-3-yl)thio)acetamide (C24H20BrClN4OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine/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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
As a certified reference material (CRM), N-(4-Bromo-2-methylphenyl)-2-((5-(4-chlorophenyl)-4-(p-tolyl)-4H-1,2,4-triazol-3-yl)thio)acetamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
