Chemical Structure

6-(Bromomethyl)-5-fluoro-2H-benzo[b][1,4]oxazin-3(4H)-one CAS 2883020-29-7 chemical structure

Description

The occurrence of 6-(Bromomethyl)-5-fluoro-2H-benzo[b][1,4]oxazin-3(4H)-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 6-(Bromomethyl)-5-fluoro-2H-benzo[b][1,4]oxazin-3(4H)-one (CAS 2883020-29-7), a certified reference material (molecular formula C9H7BrFNO2, MW 260.06 g/mol) for analytical method development and quality control.

6-(Bromomethyl)-5-fluoro-2H-benzo[b][1,4]oxazin-3(4H)-one (C9H7BrFNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), 6-(Bromomethyl)-5-fluoro-2H-benzo[b][1,4]oxazin-3(4H)-one 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.
