4-(5-aminopent-1-ynyl)-2-(2,6-dioxo-3-piperidyl)isoindoline-1,3-dione (CAS 2300976-25-2), molecular formula C18H17N3O4 and molecular weight 339.35 g/mol, is a CATO reference standard with documented purity and traceability.
4-(5-aminopent-1-ynyl)-2-(2,6-dioxo-3-piperidyl)isoindoline-1,3-dione (C18H17N3O4) contains a flavonoid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
