Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 513.39 g/mol gives p-DANPHOS distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies p-DANPHOS (CAS 1289463-79-1), a certified reference material (molecular formula C19H14F3O6PS2Na, MW 513.39 g/mol) for analytical method development and quality control.
The molecular framework of p-DANPHOS (C19H14F3O6PS2Na) is characterized by a flavonoid core, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage, fluorine substitution. 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. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
