Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 332.91 g/mol gives 1-Bromo-3-(difluoromethyl)-5-iodobenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Bromo-3-(difluoromethyl)-5-iodobenzene (CAS 1261476-63-4), molecular formula C7H4BrF2I and molecular weight 332.91 g/mol, is a CATO reference standard with documented purity and traceability.
1-Bromo-3-(difluoromethyl)-5-iodobenzene (C7H4BrF2I) contains fluorine/bromine/iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
