Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 375.83 g/mol gives 4-Bromo-2-iodobenzyl bromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Bromo-2-iodobenzyl bromide (CAS 885681-96-9), a certified reference material (molecular formula C7H5Br2I, MW 375.83 g/mol) for analytical method development and quality control.
Structurally, 4-Bromo-2-iodobenzyl bromide (C7H5Br2I) contains bromine/iodine 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 375.83 g/mol, it falls into the moderately-high-molecular-weight range. 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.
