Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-Bromo-3-chloro-4-fluoro-2-iodobenzene (CAS 2226439-58-1), molecular formula C6H2BrClFI and molecular weight 335.34 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine/chlorine/bromine/iodine substitution, an aromatic ring system, 1-Bromo-3-chloro-4-fluoro-2-iodobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 335.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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.
