Chemical Structure

Disodium hydrogen phosphate dihydrate CAS 10028-24-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Disodium hydrogen phosphate dihydrate.

Disodium hydrogen phosphate dihydrate (CAS 10028-24-7), molecular formula HO4PNaH2O and molecular weight 136.98 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula HO4PNaH2O, Disodium hydrogen phosphate dihydrate contains a phosphate ester group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 136.98 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
