Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 310.02 g/mol gives 6-Bromo-7-(trifluoromethyl)-2H-benzo[d][1,3]oxazine-2,4(1H)-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
6-Bromo-7-(trifluoromethyl)-2H-benzo[d][1,3]oxazine-2,4(1H)-dione (CAS 1820740-28-0), molecular formula C9H3BrF3NO3 and molecular weight 310.02 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-Bromo-7-(trifluoromethyl)-2H-benzo[d][1,3]oxazine-2,4(1H)-dione (C9H3BrF3NO3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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.
CATO manufactures 6-Bromo-7-(trifluoromethyl)-2H-benzo[d][1,3]oxazine-2,4(1H)-dione 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.
