Chemical Structure
Description
The occurrence of Antimonate(5-), bis[4,5-di(hydroxy-κO)-1,3-benzenedisulfonato(4-)]-, pentasodium, (T-4)- is closely related to a carbohydrate-derived structure, a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Antimonate(5-), bis[4,5-di(hydroxy-κO)-1,3-benzenedisulfonato(4-)]-, pentasodium, (T-4)- (CAS 23940-36-5) is a high-purity analytical reference standard with the molecular formula C12H4O16S4SbNa and a molecular weight of 677.14 g/mol.
Antimonate(5-), bis[4,5-di(hydroxy-κO)-1,3-benzenedisulfonato(4-)]-, pentasodium, (T-4)- (C12H4O16S4SbNa) 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).
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.
