Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 203.06 g/mol gives Dihydroxytartaric Acid Disodium Salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dihydroxytartaric Acid Disodium Salt (CAS 866-17-1), molecular formula C4H4O8Na and molecular weight 203.06 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Dihydroxytartaric Acid Disodium Salt (C4H4O8Na) contains a carbohydrate-derived structure. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 203.06 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.
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.
