Chemical Structure

Sodium Phenyl Phosphate Dibasic Dihydrate CAS 66778-08-3 chemical structure

Description

CATO supplies Sodium Phenyl Phosphate Dibasic Dihydrate (CAS 66778-08-3), a certified reference material (molecular formula C6H5O4PNaH2O, MW 213.08 g/mol) for analytical method development and quality control.

The molecular framework of Sodium Phenyl Phosphate Dibasic Dihydrate (C6H5O4PNaH2O) is characterized by a carbohydrate-derived structure, a phosphate ester group. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 Phenyl Phosphate Dibasic Dihydrate 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.
