Chemical Structure

Maleate trihydrate (sodium) CAS 3105-55-3 chemical structure

Description

Owing to a carbohydrate-derived structure, Maleate trihydrate (sodium) is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 138.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

Maleate trihydrate (sodium) (CAS 3105-55-3) is a high-purity analytical reference standard with the molecular formula C4H3NaO4 and a molecular weight of 138.05 g/mol.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), Maleate trihydrate (sodium) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
