1-(4-Chlorophenyl)-2-((5-methyl-4h-1,2,4-triazol-3-yl)thio)ethan-1-one CAS 37664-34-9

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.

1-(4-Chlorophenyl)-2-((5-methyl-4h-1,2,4-triazol-3-yl)thio)ethan-1-one (CAS 37664-34-9) is a high-purity analytical reference standard with the molecular formula C11H10ClN3OS and a molecular weight of 267.73 g/mol.

Based on its molecular formula C11H10ClN3OS, 1-(4-Chlorophenyl)-2-((5-methyl-4h-1,2,4-triazol-3-yl)thio)ethan-1-one contains a nitrogen-containing heterocyclic scaffold, 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 267.73 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
