Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Sodium 2-(1,3-dioxo-2,3-dihydro-1H-inden-2-yl)-8-methylquinoline-6-sulfonate.
Sodium 2-(1,3-dioxo-2,3-dihydro-1H-inden-2-yl)-8-methylquinoline-6-sulfonate (CAS 83929-58-2) is a high-purity analytical reference standard with the molecular formula C19H12NO5SNa and a molecular weight of 389.36 g/mol.
Sodium 2-(1,3-dioxo-2,3-dihydro-1H-inden-2-yl)-8-methylquinoline-6-sulfonate (C19H12NO5SNa) contains a flavonoid core, an amide group, a sulfone 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.
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.
