Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 245.25 g/mol gives 2-Oxo-3,4-dihydro-1H-quinoline-6-sulfonic acid hydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-Oxo-3,4-dihydro-1H-quinoline-6-sulfonic acid hydrate (CAS 1437794-84-7), a certified reference material (molecular formula C9H9NO4SH2O, MW 245.25 g/mol) for analytical method development and quality control.
2-Oxo-3,4-dihydro-1H-quinoline-6-sulfonic acid hydrate (C9H9NO4SH2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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.
