Chemical Structure

Pyrimidine-2,4,5-triamine CAS 3546-50-7 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 Pyrimidine-2,4,5-triamine (CAS 3546-50-7), a certified reference material (molecular formula C4H7N5, MW 125.13 g/mol) for analytical method development and quality control.

Owing to a nitrile group, Pyrimidine-2,4,5-triamine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 125.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
