Compared with other compounds in its class, the molecular weight of 434.94 g/mol gives 2-((5-(4-Chlorophenyl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)-N-(p-tolyl)acetamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-((5-(4-Chlorophenyl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)-N-(p-tolyl)acetamide (CAS 332922-53-9), molecular formula C23H19ClN4OS and molecular weight 434.94 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-((5-(4-Chlorophenyl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)-N-(p-tolyl)acetamide (C23H19ClN4OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, 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. 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.
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.
