Chemical Structure
Description
CATO supplies 4-Chloro-5-ethoxy-2-methylpyrimidine (CAS 24611-12-9), a certified reference material (molecular formula C7H9ClN2O, MW 172.61 g/mol) for analytical method development and quality control.
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 4-Chloro-5-ethoxy-2-methylpyrimidine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 172.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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-ethoxy-2-methylpyrimidine 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.
