Chemical Structure
Description
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.
2-(1,3-Dioxo-1H-benzo[de]isoquinolin-2(3H)-yl)butanamide (CAS 5840-54-0), molecular formula C15H33Cl2NO5Si and molecular weight 406.42 g/mol, is a CATO reference standard with documented purity and traceability.
2-(1,3-Dioxo-1H-benzo[de]isoquinolin-2(3H)-yl)butanamide (C15H33Cl2NO5Si) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
