Chemical Structure
Description
As a certified reference material (CRM), 2,3-Epoxysuccinic acid disodium salt 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.
2,3-Epoxysuccinic acid disodium salt (CAS 40618-18-6), molecular formula C4H2O5Na and molecular weight 153.04 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2,3-Epoxysuccinic acid disodium salt (C4H2O5Na) contains a carbohydrate-derived structure. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 153.04 g/mol, it falls into the medium-molecular-weight range. 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.
