Chemical Structure
Description
The occurrence of Thiodiglycolic Acid-d4 is closely related to deuterium isotope labeling, a carbohydrate-derived structure, a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Thiodiglycolic Acid-d4 (CAS 132090-51-8), molecular formula C4H2D4O4S and molecular weight 154.18 g/mol, is a CATO reference standard with documented purity and traceability.
Thiodiglycolic Acid-d4 (C4H2D4O4S) contains deuterium isotope labeling, a carbohydrate-derived structure, a sulfone group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
