2-(((3-Carboxyoxazolidin-5-yl)oxy)carbonyl)oxazolidine-3-carboxylic acid (CAS 62935-85-7), molecular formula C5H5NO5 and molecular weight 159.10 g/mol, is a CATO reference standard with documented purity and traceability.
2-(((3-Carboxyoxazolidin-5-yl)oxy)carbonyl)oxazolidine-3-carboxylic acid (C5H5NO5) contains a carbohydrate-derived structure, an amide 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).
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.
