Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-Bromo-3-fluorobenzyl bromide, 97% (CAS 127425-73-4) is a high-purity analytical reference standard with the molecular formula C7H5Br2F and a molecular weight of 267.92 g/mol.
Owing to fluorine/bromine substitution, an aromatic ring system, 4-Bromo-3-fluorobenzyl bromide, 97% is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 267.92 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
