Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 246.21 g/mol gives 2,2’-Difluorobenzil distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,2’-Difluorobenzil (CAS 573-43-3), molecular formula C14H8F2O2 and molecular weight 246.21 g/mol, is a CATO reference standard with documented purity and traceability.
2,2’-Difluorobenzil (C14H8F2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2,2’-Difluorobenzil under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
