Chemical Structure

Potassium Phosphate Monobasic CAS 7778-77-0 chemical structure

Description

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

Potassium Phosphate Monobasic (CAS 7778-77-0), molecular formula H2KO4P and molecular weight 136.08 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a phosphate ester group, Potassium Phosphate Monobasic is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 136.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
