Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
8-Bromo-3,4-dihydro-2H-pyrido[4,3-b][1,4]oxazine (CAS 1379320-13-4), molecular formula C7H7BrN2O and molecular weight 215.05 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 8-Bromo-3,4-dihydro-2H-pyrido[4,3-b][1,4]oxazine (C7H7BrN2O) is characterized by an amide group, a hydroxyl group, an ether linkage, bromine substitution, 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), 8-Bromo-3,4-dihydro-2H-pyrido[4,3-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.
