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.

4-(3-(3-Chlorophenyl)-1H-1,2,4-triazol-5-yl)-2-methoxyphenol (CAS 1416345-38-4), molecular formula C15H12ClN3O2 and molecular weight 301.73 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C15H12ClN3O2, 4-(3-(3-Chlorophenyl)-1H-1,2,4-triazol-5-yl)-2-methoxyphenol contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 301.73 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
