3-(4-Methoxyphenyl)-4-phenyl-4H-1,2,4-triazole CAS 70187-22-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(4-Methoxyphenyl)-4-phenyl-4H-1,2,4-triazole.

CATO supplies 3-(4-Methoxyphenyl)-4-phenyl-4H-1,2,4-triazole (CAS 70187-22-3), a certified reference material (molecular formula C15H13N3O, MW 251.28 g/mol) for analytical method development and quality control.

Based on its molecular formula C15H13N3O, 3-(4-Methoxyphenyl)-4-phenyl-4H-1,2,4-triazole contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 251.28 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.

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.
