Description
CATO supplies 7-Chloro-2-(p-tolyl)oxazolo[5,4-d]pyrimidine (CAS 1018142-92-1), a certified reference material (molecular formula C12H8ClN3O, MW 245.66 g/mol) for analytical method development and quality control.
7-Chloro-2-(p-tolyl)oxazolo[5,4-d]pyrimidine (C12H8ClN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 7-Chloro-2-(p-tolyl)oxazolo[5,4-d]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.
