Chemical Structure
Description
(3,4-Difluorophenyl)(3-fluorophenyl)methanone (C13H7F3O) contains a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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).
(3,4-Difluorophenyl)(3-fluorophenyl)methanone (CAS 951885-75-9) is a high-purity analytical reference standard with the molecular formula C13H7F3O and a molecular weight of 236.19 g/mol.
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-Difluorophenyl)(3-fluorophenyl)methanone 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.
