Chemical Structure
Description
As a certified reference material (CRM), 4-Chloro-2-(4-methoxyphenyl)-6-methylpyrimidine 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.
CATO supplies 4-Chloro-2-(4-methoxyphenyl)-6-methylpyrimidine (CAS 142245-40-7), a certified reference material (molecular formula C12H11ClN2O, MW 234.68 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 4-Chloro-2-(4-methoxyphenyl)-6-methylpyrimidine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 234.68 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
