Chemical Structure

5-Methyl-7-(naphthalen-2-yl)-[1,2,4]triazolo[1,5-a]pyrimidine CAS 478041-01-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Methyl-7-(naphthalen-2-yl)-[1,2,4]triazolo[1,5-a]pyrimidine.

CATO supplies 5-Methyl-7-(naphthalen-2-yl)-[1,2,4]triazolo[1,5-a]pyrimidine (CAS 478041-01-9), a certified reference material (molecular formula C16H12N4, MW 260.29 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 5-Methyl-7-(naphthalen-2-yl)-[1,2,4]triazolo[1,5-a]pyrimidine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 260.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
