Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 180.09 g/mol gives Sodium 2,4-difluorobenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Sodium 2,4-difluorobenzoate (CAS 1765-08-8), molecular formula C7H3F2O2Na and molecular weight 180.09 g/mol, is a CATO reference standard with documented purity and traceability.
Sodium 2,4-difluorobenzoate (C7H3F2O2Na) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, 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 Sodium 2,4-difluorobenzoate 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.
