Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 389.85 g/mol gives 2,4-Dibromo-3,6-dimethyliodobenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,4-Dibromo-3,6-dimethyliodobenzene (CAS 1160574-09-3) is a high-purity analytical reference standard with the molecular formula C8H7Br2I and a molecular weight of 389.85 g/mol.
Owing to bromine/iodine substitution, an aromatic ring system, 2,4-Dibromo-3,6-dimethyliodobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 389.85 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).
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.
