Description
As a certified reference material (CRM), 1,5-Dibromo-2-difluoromethoxy-4-fluorobenzene 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-difluoromethoxy-4-fluorobenzene (CAS 1804515-34-1) is a high-purity analytical reference standard with the molecular formula C7H3Br2F3O and a molecular weight of 319.90 g/mol.
1,5-Dibromo-2-difluoromethoxy-4-fluorobenzene (C7H3Br2F3O) contains a hydroxyl group, an ether linkage, fluorine/bromine 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
