Chemical Structure
Description
The occurrence of DL-Malic Acid-2,3,3-d3 is closely related to deuterium isotope labeling, a carbohydrate-derived structure in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
DL-Malic Acid-2,3,3-d3 (CAS 104596-63-6), molecular formula C4H3D3O5 and molecular weight 137.11 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, a carbohydrate-derived structure, DL-Malic Acid-2,3,3-d3 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 137.11 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).
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.
