Chemical Structure
Description
1',4'-Dihydro-3'H-spiro[piperidine-4,2'-quinoxalin]-3'-one hydrochloride (CAS 1609403-99-7), molecular formula C12H15N3OHCl and molecular weight 253.73 g/mol, is a CATO reference standard with documented purity and traceability.
1',4'-Dihydro-3'H-spiro[piperidine-4,2'-quinoxalin]-3'-one hydrochloride (C12H15N3OHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
