Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 291.01 g/mol gives 1-(Bromomethyl)-2,4-difluoro-3-(trifluoromethoxy)benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(Bromomethyl)-2,4-difluoro-3-(trifluoromethoxy)benzene (CAS 2149591-35-3), molecular formula C8H4BrF5O and molecular weight 291.01 g/mol, is a CATO reference standard with documented purity and traceability.
1-(Bromomethyl)-2,4-difluoro-3-(trifluoromethoxy)benzene (C8H4BrF5O) contains a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
