Chemical Structure
Description
3,5-Dichloro-4-(difluoromethoxy)benzodifluoride (CAS 1806296-77-4) is a high-purity analytical reference standard with the molecular formula C8H4Cl2F4O and a molecular weight of 263.02 g/mol.
3,5-Dichloro-4-(difluoromethoxy)benzodifluoride (C8H4Cl2F4O) contains a hydroxyl group, an ether linkage, fluorine/chlorine 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.
As a certified reference material (CRM), 3,5-Dichloro-4-(difluoromethoxy)benzodifluoride 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.
