Chemical Structure
Description
The molecular framework of 3-{2,5-dimethyl-7-oxo-3-phenyl-4h,7h-pyrazolo[1,5-a]pyrimidin-6-yl}propanoic acid (C17H17N3O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
3-{2,5-dimethyl-7-oxo-3-phenyl-4h,7h-pyrazolo[1,5-a]pyrimidin-6-yl}propanoic acid (CAS 878417-25-5), molecular formula C17H17N3O3 and molecular weight 311.34 g/mol, is a CATO reference standard with documented purity and traceability.
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), 3-{2,5-dimethyl-7-oxo-3-phenyl-4h,7h-pyrazolo[1,5-a]pyrimidin-6-yl}propanoic 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.
