Chemical Structure
Description
CATO supplies 6-amino-7-fluoro-2H,3H,4H-pyrido[3,2-b][1,4]oxazin-3-one (CAS 1909347-79-0), a certified reference material (molecular formula C7H6FN3O2, MW 183.14 g/mol) for analytical method development and quality control.
The molecular framework of 6-amino-7-fluoro-2H,3H,4H-pyrido[3,2-b][1,4]oxazin-3-one (C7H6FN3O2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
