Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 330.18 g/mol gives Diflunisal Phosphate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Diflunisal Phosphate (CAS 84958-45-2), molecular formula C13H9F2O6P and molecular weight 330.18 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, Diflunisal Phosphate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 330.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Diflunisal Phosphate 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.
