7-(1-Ethyl-3-methyl-1h-pyrazol-4-yl)pyrazolo[1,5-a]pyrimidine-3-carboxylic acid (CAS 1001500-35-1) is a high-purity analytical reference standard with the molecular formula C13H13N5O2 and a molecular weight of 271.27 g/mol.
7-(1-Ethyl-3-methyl-1h-pyrazol-4-yl)pyrazolo[1,5-a]pyrimidine-3-carboxylic acid (C13H13N5O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
