2-Methyl-4-[4-(1H-1,2,4-triazol-1-yl)phenyl]pyrimidine CAS 685107-79-3 chemical structure

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.

2-Methyl-4-[4-(1H-1,2,4-triazol-1-yl)phenyl]pyrimidine (CAS 685107-79-3), molecular formula C13H11N5 and molecular weight 237.26 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-Methyl-4-[4-(1H-1,2,4-triazol-1-yl)phenyl]pyrimidine (C13H11N5) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 237.26 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
