5-[(Z)-2-(2-Chlorophenyl)diazen-1-yl]-4-phenyl-2-(pyridin-4-yl)pyrimidine CAS 339279-60-6

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 5-[(Z)-2-(2-Chlorophenyl)diazen-1-yl]-4-phenyl-2-(pyridin-4-yl)pyrimidine (CAS 339279-60-6), a certified reference material (molecular formula C21H14ClN5, MW 371.82 g/mol) for analytical method development and quality control.

Based on its molecular formula C21H14ClN5, 5-[(Z)-2-(2-Chlorophenyl)diazen-1-yl]-4-phenyl-2-(pyridin-4-yl)pyrimidine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 371.82 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
