2-(4-Chlorophenyl)-5-methyl-N-(pyridin-4-yl)pyrimidin-4-amine CAS 674794-42-4

Description

2-(4-Chlorophenyl)-5-methyl-N-(pyridin-4-yl)pyrimidin-4-amine (CAS 674794-42-4), molecular formula C16H13ClN4 and molecular weight 296.75 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(4-Chlorophenyl)-5-methyl-N-(pyridin-4-yl)pyrimidin-4-amine (C16H13ClN4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
