Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Methoxy-N'-(thieno[2,3-b]quinoline-2-carbonyl)benzenesulfonohydrazide.
4-Methoxy-N'-(thieno[2,3-b]quinoline-2-carbonyl)benzenesulfonohydrazide (CAS 692260-16-5) is a high-purity analytical reference standard with the molecular formula C19H15N3O4S2 and a molecular weight of 413.47 g/mol.
4-Methoxy-N'-(thieno[2,3-b]quinoline-2-carbonyl)benzenesulfonohydrazide (C19H15N3O4S2) contains a flavonoid core, 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.
