Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 152.10 g/mol gives (+/-)-Tartaric-2,3-d distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(+/-)-Tartaric-2,3-d (CAS 91469-46-4) is a high-purity analytical reference standard with the molecular formula C4H4D2O6 and a molecular weight of 152.10 g/mol.
Based on its molecular formula C4H4D2O6, (+/-)-Tartaric-2,3-d contains deuterium isotope labeling, a carbohydrate-derived structure; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 152.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
