Description

2-((4-(4-Chlorophenyl)-5-(4-methoxyphenyl)-4H-1,2,4-triazol-3-yl)thio)-N-(2,4-dimethylphenyl)acetamide (CAS 476484-53-4), molecular formula C25H23ClN4O2S and molecular weight 478.99 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-((4-(4-Chlorophenyl)-5-(4-methoxyphenyl)-4H-1,2,4-triazol-3-yl)thio)-N-(2,4-dimethylphenyl)acetamide (C25H23ClN4O2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

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.
