4-Chloro-5,6-dimethyl-2-(pyridin-4-yl)pyrimidine CAS 204394-62-7

Description

The occurrence of 4-Chloro-5,6-dimethyl-2-(pyridin-4-yl)pyrimidine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-Chloro-5,6-dimethyl-2-(pyridin-4-yl)pyrimidine (CAS 204394-62-7), a certified reference material (molecular formula C11H10ClN3, MW 219.67 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 4-Chloro-5,6-dimethyl-2-(pyridin-4-yl)pyrimidine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 219.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
