Chemical Structure
Description
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.
3-Chloro-5-(4-methylphenyl)-4-phenyl-4h-1,2,4-triazole (CAS 108850-11-9) is a high-purity analytical reference standard with the molecular formula C15H12ClN3 and a molecular weight of 269.73 g/mol.
The molecular framework of 3-Chloro-5-(4-methylphenyl)-4-phenyl-4h-1,2,4-triazole (C15H12ClN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
