Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 259.00 g/mol gives 4-Bromo-2,3,5,6-tetrafluorobenzyl Alcohol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Bromo-2,3,5,6-tetrafluorobenzyl Alcohol (CAS 75865-45-1), molecular formula C7H3BrF4O and molecular weight 259.00 g/mol, is a CATO reference standard with documented purity and traceability.
4-Bromo-2,3,5,6-tetrafluorobenzyl Alcohol (C7H3BrF4O) 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.
