Chemical Structure

Sodium phosphate binary dodecahydrate CAS 10039-32-4 chemical structure

Description

The molecular framework of Sodium phosphate binary dodecahydrate (HO4PNaH2O) is characterized by 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.

Sodium phosphate binary dodecahydrate (CAS 10039-32-4) is a high-purity analytical reference standard with the molecular formula HO4PNaH2O and a molecular weight of 136.98 g/mol.

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.
