N-(4-Chlorophenyl)-2-((5-cyclohexyl-4-ethyl-4H-1,2,4-triazol-3-yl)thio)acetamide CAS 482650-85-1

Description

N-(4-Chlorophenyl)-2-((5-cyclohexyl-4-ethyl-4H-1,2,4-triazol-3-yl)thio)acetamide (CAS 482650-85-1), molecular formula C18H23ClN4OS and molecular weight 378.92 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C18H23ClN4OS, N-(4-Chlorophenyl)-2-((5-cyclohexyl-4-ethyl-4H-1,2,4-triazol-3-yl)thio)acetamide contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 378.92 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.

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.
