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.
CATO supplies 2-(Methylthio)-7-phenyl-[1,2,4]triazolo[1,5-a]pyrimidine (CAS 1158280-10-4), a certified reference material (molecular formula C12H10N4S, MW 242.30 g/mol) for analytical method development and quality control.
Structurally, 2-(Methylthio)-7-phenyl-[1,2,4]triazolo[1,5-a]pyrimidine (C12H10N4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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 242.30 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
