Chemical Structure

8-Fluoro-2-methyl-4H-benzo[d][1,3]oxazin-4-one CAS 1044749-59-8 chemical structure

Description

8-Fluoro-2-methyl-4H-benzo[d][1,3]oxazin-4-one (CAS 1044749-59-8) is a high-purity analytical reference standard with the molecular formula C9H6FNO2 and a molecular weight of 179.15 g/mol.

The molecular framework of 8-Fluoro-2-methyl-4H-benzo[d][1,3]oxazin-4-one (C9H6FNO2) is characterized by a nitrogen-containing heterocyclic scaffold, 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 8-Fluoro-2-methyl-4H-benzo[d][1,3]oxazin-4-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
