Chemical Structure
Description
Based on its molecular formula C11H16O10S2K, Bis(3-sulfopropyl)itaconate,dipotassiumsalt contains a carbohydrate-derived structure, a sulfone group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 411.46 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).
Bis(3-sulfopropyl)itaconate,dipotassiumsalt (CAS 93841-09-9), molecular formula C11H16O10S2K and molecular weight 411.46 g/mol, is a CATO reference standard with documented purity and traceability.
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.
