Chemical Structure
Description
The occurrence of 3,4-Difluoro-5-(trifluoromethoxy)benzodifluoride is closely related to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3,4-Difluoro-5-(trifluoromethoxy)benzodifluoride (CAS 1803789-83-4), molecular formula C8H3F7O and molecular weight 248.10 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3,4-Difluoro-5-(trifluoromethoxy)benzodifluoride (C8H3F7O) is characterized by a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), 3,4-Difluoro-5-(trifluoromethoxy)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.
