4-Chloro-5,6-dimethyl-2-(pyrimidin-2-yl)pyrimidine CAS 1179266-29-5

Description

The occurrence of 4-Chloro-5,6-dimethyl-2-(pyrimidin-2-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.

4-Chloro-5,6-dimethyl-2-(pyrimidin-2-yl)pyrimidine (CAS 1179266-29-5), molecular formula C10H9ClN4 and molecular weight 220.66 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 4-Chloro-5,6-dimethyl-2-(pyrimidin-2-yl)pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 220.66 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.

CATO manufactures 4-Chloro-5,6-dimethyl-2-(pyrimidin-2-yl)pyrimidine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
