Description
As a certified reference material (CRM), 1,5-Dibromo-2,4-difluoro-3-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.
1,5-Dibromo-2,4-difluoro-3-iodobenzene (CAS 679836-60-3) is a high-purity analytical reference standard with the molecular formula C6HBr2F2I and a molecular weight of 397.78 g/mol.
Owing to fluorine/bromine/iodine substitution, an aromatic ring system, 1,5-Dibromo-2,4-difluoro-3-iodobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 397.78 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.
