Chemical Structure

Sodium dihydrogen phosphate CAS 7758-80-7 chemical structure

Description

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

CATO supplies Sodium dihydrogen phosphate (CAS 7758-80-7), a certified reference material (molecular formula H2O4PNa, MW 119.98 g/mol) for analytical method development and quality control.

Owing to a phosphate ester group, Sodium dihydrogen phosphate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 119.98 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.

CATO manufactures Sodium dihydrogen phosphate 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.
