5-(1,3-dimethyl-1H-pyrazol-4-yl)-2-(trifluoromethyl)pyrazolo[1,5-a]pyrimidine-7-carboxylic acid (CAS 1171045-38-7) is a high-purity analytical reference standard with the molecular formula C13H10F3N5O2 and a molecular weight of 325.25 g/mol.
5-(1,3-dimethyl-1H-pyrazol-4-yl)-2-(trifluoromethyl)pyrazolo[1,5-a]pyrimidine-7-carboxylic acid (C13H10F3N5O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
CATO manufactures 5-(1,3-dimethyl-1H-pyrazol-4-yl)-2-(trifluoromethyl)pyrazolo[1,5-a]pyrimidine-7-carboxylic acid 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.
