Chemical Structure
Description
7-(p-Tolyl)-[1,2,4]triazolo[1,5-a]pyrimidine (CAS 160290-38-0) is a high-purity analytical reference standard with the molecular formula C12H10N4 and a molecular weight of 210.23 g/mol.
Structurally, 7-(p-Tolyl)-[1,2,4]triazolo[1,5-a]pyrimidine (C12H10N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 210.23 g/mol, it falls into the medium-molecular-weight range. 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.
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.
