Chemical Structure
Description
N-(2,5-dioxo-1-(piperidin-1-yl)-1,2,5,6,7,8-hexahydroquinolin-3-yl)benzamide (C21H23N3O3) contains a steroid core, an amide 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).
N-(2,5-dioxo-1-(piperidin-1-yl)-1,2,5,6,7,8-hexahydroquinolin-3-yl)benzamide (CAS 400078-25-3), molecular formula C21H23N3O3 and molecular weight 365.43 g/mol, is a CATO reference standard with documented purity and traceability.
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.
