Chemical Structure
Description
The occurrence of 4-Chloro-5,6-dimethyl-2-(pyridin-3-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-3-yl)pyrimidine (CAS 204394-64-9), a certified reference material (molecular formula C11H10ClN3, MW 219.67 g/mol) for analytical method development and quality control.
The molecular framework of 4-Chloro-5,6-dimethyl-2-(pyridin-3-yl)pyrimidine (C11H10ClN3) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4-Chloro-5,6-dimethyl-2-(pyridin-3-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.
