7-bromo-4-fluoro-3H-1,3-benzoxazol-2-one CAS 2387598-51-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 238.05 g/mol gives 7-bromo-4-fluoro-3H-1,3-benzoxazol-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

7-bromo-4-fluoro-3H-1,3-benzoxazol-2-one (CAS 2387598-51-6), molecular formula C7H9BrFNO2 and molecular weight 238.05 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 7-bromo-4-fluoro-3H-1,3-benzoxazol-2-one (C7H9BrFNO2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine 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.

As a certified reference material (CRM), 7-bromo-4-fluoro-3H-1,3-benzoxazol-2-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.
