Description
Compared with other compounds in its class, the molecular weight of 244.12 g/mol gives 3-(tert-Butyl)-5,7-dichloroimidazo[1,5-c]pyrimidine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(tert-Butyl)-5,7-dichloroimidazo[1,5-c]pyrimidine (CAS 94694-13-0), molecular formula C10H11Cl2N3 and molecular weight 244.12 g/mol, is a CATO reference standard with documented purity and traceability.
3-(tert-Butyl)-5,7-dichloroimidazo[1,5-c]pyrimidine (C10H11Cl2N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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), 3-(tert-Butyl)-5,7-dichloroimidazo[1,5-c]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.
