Chemical Structure
Description
The occurrence of Potassium 2,5-dihydroxybenzene-1,3-disulfonate is closely related to a carbohydrate-derived structure, a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Potassium 2,5-dihydroxybenzene-1,3-disulfonate (CAS 51579-80-7), a certified reference material (molecular formula C6H4O8S2K, MW 307.31 g/mol) for analytical method development and quality control.
Structurally, Potassium 2,5-dihydroxybenzene-1,3-disulfonate (C6H4O8S2K) contains a carbohydrate-derived structure, a sulfone group. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 307.31 g/mol, it falls into the moderately-high-molecular-weight range. 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.
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.
