Chemical Structure
Description
CATO supplies 4-(Methylamino)-2-((4-methylbenzyl)thio)-6-phenylpyrimidine-5-carbonitrile (CAS 320422-38-6), a certified reference material (molecular formula C20H18N4S, MW 346.45 g/mol) for analytical method development and quality control.
Based on its molecular formula C20H18N4S, 4-(Methylamino)-2-((4-methylbenzyl)thio)-6-phenylpyrimidine-5-carbonitrile contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 346.45 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
