Description
As a certified reference material (CRM), 4,5-Dichloro-2-(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.
CATO supplies 4,5-Dichloro-2-(difluoromethoxy)benzodifluoride (CAS 1803712-62-0), a certified reference material (molecular formula C8H4Cl2F4O, MW 263.02 g/mol) for analytical method development and quality control.
The molecular framework of 4,5-Dichloro-2-(difluoromethoxy)benzodifluoride (C8H4Cl2F4O) is characterized by a hydroxyl group, an ether linkage, fluorine/chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
