(S)-Isothiazolidine-3-carboxylic acid 1,1-dioxide (CAS 147878-93-1), molecular formula C4H7NO4S and molecular weight 165.17 g/mol, is a CATO reference standard with documented purity and traceability.
(S)-Isothiazolidine-3-carboxylic acid 1,1-dioxide (C4H7NO4S) contains a carbohydrate-derived structure, an amide group, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
