Chemical Structure
Description
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.
CATO supplies sodium 4-(pivaloyloxy)benzene-1,3-disulfonate (CAS CATO-C4X-212339), a certified reference material (molecular formula C11H12O8S2Na, MW 359.32 g/mol) for analytical method development and quality control.
sodium 4-(pivaloyloxy)benzene-1,3-disulfonate (C11H12O8S2Na) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
