Chemical Structure
Description
CATO supplies 1-bromo-3-(bromomethyl)-2,4-difluorobenzene (CAS 438050-04-5), a certified reference material (molecular formula C7H4Br2F2, MW 285.91 g/mol) for analytical method development and quality control.
Structurally, 1-bromo-3-(bromomethyl)-2,4-difluorobenzene (C7H4Br2F2) contains fluorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 285.91 g/mol, it falls into the medium-molecular-weight range. 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).
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.
