Chemical Structure

Potassium phosphate binary trihydrate CAS 16788-57-1 chemical structure

Description

The occurrence of Potassium phosphate binary trihydrate is closely related to a phosphate ester group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Potassium phosphate binary trihydrate (CAS 16788-57-1), a certified reference material (molecular formula HO4PKH2O, MW 153.09 g/mol) for analytical method development and quality control.

Potassium phosphate binary trihydrate (HO4PKH2O) contains a phosphate ester group. It is notably hygroscopic; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
