Chemical Structure

(R)-6-Bromo-8-fluoro-2-methyl-2H-benzo[b][1,4]oxazin-3(4H)-one CAS 1798336-08-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (R)-6-Bromo-8-fluoro-2-methyl-2H-benzo[b][1,4]oxazin-3(4H)-one.

CATO supplies (R)-6-Bromo-8-fluoro-2-methyl-2H-benzo[b][1,4]oxazin-3(4H)-one (CAS 1798336-08-9), a certified reference material (molecular formula C9H7BrFNO2, MW 260.06 g/mol) for analytical method development and quality control.

Structurally, (R)-6-Bromo-8-fluoro-2-methyl-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. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 260.06 g/mol, it falls into the medium-molecular-weight range. 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.

CATO manufactures (R)-6-Bromo-8-fluoro-2-methyl-2H-benzo[b][1,4]oxazin-3(4H)-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.
