Description
CATO supplies 7-(Chlorodifluoromethyl)-5-methyl-3-(thiophen-2-yl)pyrazolo[1,5-a]pyrimidine (CAS 692733-12-3), a certified reference material (molecular formula C12H8ClF2N3S, MW 299.73 g/mol) for analytical method development and quality control.
7-(Chlorodifluoromethyl)-5-methyl-3-(thiophen-2-yl)pyrazolo[1,5-a]pyrimidine (C12H8ClF2N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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-(Chlorodifluoromethyl)-5-methyl-3-(thiophen-2-yl)pyrazolo[1,5-a]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.
