Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Diethyl 7-(trifluoromethyl)pyrazolo[1,5-a]pyrimidine-3,5-dicarboxylate (CAS 937601-37-1), molecular formula C13H12F3N3O4 and molecular weight 331.25 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Diethyl 7-(trifluoromethyl)pyrazolo[1,5-a]pyrimidine-3,5-dicarboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 331.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), Diethyl 7-(trifluoromethyl)pyrazolo[1,5-a]pyrimidine-3,5-dicarboxylate 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.
