Chemical Structure

Calcium Malate CAS 17482-42-7 chemical structure

Description

The occurrence of Calcium Malate is closely related to a carbohydrate-derived structure in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Calcium Malate (CAS 17482-42-7), a certified reference material (molecular formula C4H4O5Ca, MW 172.15 g/mol) for analytical method development and quality control.

The molecular framework of Calcium Malate (C4H4O5Ca) is characterized by a carbohydrate-derived structure. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

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.
