Chemical Structure
Description
The occurrence of 4-Chloro-6-methyl-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.
CATO supplies 4-Chloro-6-methyl-2-(pyrimidin-2-yl)pyrimidine (CAS 1153093-46-9), a certified reference material (molecular formula C9H7ClN4, MW 206.63 g/mol) for analytical method development and quality control.
4-Chloro-6-methyl-2-(pyrimidin-2-yl)pyrimidine (C9H7ClN4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-Chloro-6-methyl-2-(pyrimidin-2-yl)pyrimidine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
