Chemical Structure

Sodium maleate dihydrate CAS 25880-69-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 155.06 g/mol gives Sodium maleate dihydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Sodium maleate dihydrate (CAS 25880-69-7), a certified reference material (molecular formula C4H2O4NaH2O, MW 155.06 g/mol) for analytical method development and quality control.

Sodium maleate dihydrate (C4H2O4NaH2O) contains a carbohydrate-derived structure. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 maleate dihydrate 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.
