Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Calcium (2R,3S)-2,3-dihydroxysuccinate (CAS 815-79-2), molecular formula C4H4O6Ca and molecular weight 188.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carbohydrate-derived structure, Calcium (2R,3S)-2,3-dihydroxysuccinate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 188.15 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).
As a certified reference material (CRM), Calcium (2R,3S)-2,3-dihydroxysuccinate 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.
