Chemical Structure
Description
Owing to bromine/iodine substitution, 1-bromo-2-(bromomethyl)-4-iodobenzene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 381.87 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
1-bromo-2-(bromomethyl)-4-iodobenzene (CAS 289617-98-7), molecular formula C7H11Br2I and molecular weight 381.87 g/mol, is a CATO reference standard with documented purity and traceability.
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.
