2,4-Dimethyl-5-phenyl-2,4-dihydro-3H-1,2,4-triazol-3-one CAS 944-91-2

Description

The molecular framework of 2,4-Dimethyl-5-phenyl-2,4-dihydro-3H-1,2,4-triazol-3-one (C10H11N3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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).

2,4-Dimethyl-5-phenyl-2,4-dihydro-3H-1,2,4-triazol-3-one (CAS 944-91-2) is a high-purity analytical reference standard with the molecular formula C10H11N3O and a molecular weight of 189.21 g/mol.

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.
