2-((5-(4-Chlorophenyl)-4-(p-tolyl)-4H-1,2,4-triazol-3-yl)thio)-N-(3-fluoro-4-methylphenyl)acetamide CAS 477330-91-9

Description

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.

2-((5-(4-Chlorophenyl)-4-(p-tolyl)-4H-1,2,4-triazol-3-yl)thio)-N-(3-fluoro-4-methylphenyl)acetamide (CAS 477330-91-9) is a high-purity analytical reference standard with the molecular formula C24H20ClFN4OS and a molecular weight of 466.96 g/mol.

Based on its molecular formula C24H20ClFN4OS, 2-((5-(4-Chlorophenyl)-4-(p-tolyl)-4H-1,2,4-triazol-3-yl)thio)-N-(3-fluoro-4-methylphenyl)acetamide contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 466.96 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
