Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 238.24 g/mol gives Benzenedisulfonic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Benzenedisulfonic acid (CAS 30496-93-6), molecular formula C6H6O6S2 and molecular weight 238.24 g/mol, is a CATO reference standard with documented purity and traceability.
Benzenedisulfonic acid (C6H6O6S2) contains 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
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.
