Chemical Structure
Description
6-(Piperazin-1-ylsulfonyl)-1,4-dihydroquinoxaline-2,3-dione hydrochloride (C12H14N4O4SHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
6-(Piperazin-1-ylsulfonyl)-1,4-dihydroquinoxaline-2,3-dione hydrochloride (CAS 1170179-68-6) is a high-purity analytical reference standard with the molecular formula C12H14N4O4SHCl and a molecular weight of 346.79 g/mol.
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.
