Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 300.89 g/mol gives 4-Bromo-1-fluoro-2-iodobenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Bromo-1-fluoro-2-iodobenzene (CAS 116272-41-4) is a high-purity analytical reference standard with the molecular formula C6H3BrFI and a molecular weight of 300.89 g/mol.
Structurally, 4-Bromo-1-fluoro-2-iodobenzene (C6H3BrFI) contains fluorine/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 300.89 g/mol, it falls into the moderately-high-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.
As a certified reference material (CRM), 4-Bromo-1-fluoro-2-iodobenzene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
