Chemical Structure
Description
As a certified reference material (CRM), 2-(3-Oxo-3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazin-2-yl)ethyl 4-fluorobenzoate 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.
CATO supplies 2-(3-Oxo-3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazin-2-yl)ethyl 4-fluorobenzoate (CAS 866018-89-5), a certified reference material (molecular formula C16H13FN2O4, MW 316.28 g/mol) for analytical method development and quality control.
The molecular framework of 2-(3-Oxo-3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazin-2-yl)ethyl 4-fluorobenzoate (C16H13FN2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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 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.
