Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,3-dimethyl-1H,4H,5H,6H-pyrazolo[3,4-b][1,4]oxazine (CAS 1384430-50-5), molecular formula C7H11N3O and molecular weight 153.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,3-dimethyl-1H,4H,5H,6H-pyrazolo[3,4-b][1,4]oxazine (C7H11N3O) is characterized by an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. 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).
As a certified reference material (CRM), 1,3-dimethyl-1H,4H,5H,6H-pyrazolo[3,4-b][1,4]oxazine 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.
