Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 225.01 g/mol gives 2,4,5-Trifluorobenzyl Bromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,4,5-Trifluorobenzyl Bromide (CAS 157911-56-3) is a high-purity analytical reference standard with the molecular formula C7H4BrF3 and a molecular weight of 225.01 g/mol.
2,4,5-Trifluorobenzyl Bromide (C7H4BrF3) contains 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.
