The occurrence of 25940-35-6 3-pyrazolo[1,5-a]pyrimidinecarboxylic acid A818097 pyrazolo[1,5-a]pyrimidine-3-carboxylic acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 25940-35-6 3-pyrazolo[1,5-a]pyrimidinecarboxylic acid A818097 pyrazolo[1,5-a]pyrimidine-3-carboxylic acid (CAS 25940-35-6), a certified reference material (molecular formula C7H13N3O2, MW 171.20 g/mol) for analytical method development and quality control.
25940-35-6 3-pyrazolo[1,5-a]pyrimidinecarboxylic acid A818097 pyrazolo[1,5-a]pyrimidine-3-carboxylic acid (C7H13N3O2) contains an amino-acid-derived structure, 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.
As a certified reference material (CRM), 25940-35-6 3-pyrazolo[1,5-a]pyrimidinecarboxylic acid A818097 pyrazolo[1,5-a]pyrimidine-3-carboxylic acid 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.
