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.
Sodium 5,5',5''-phosphanetriyltris(2,4-dimethylbenzenesulfonate) hydrate (CAS 1166403-40-2) is a high-purity analytical reference standard with the molecular formula C24H24O9PS3NaH2O and a molecular weight of 624.61 g/mol.
Sodium 5,5',5''-phosphanetriyltris(2,4-dimethylbenzenesulfonate) hydrate (C24H24O9PS3NaH2O) contains a flavonoid core, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage. 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.
