2’,3’-Dihydrospiro[imidazolidine-4,1’-indene]-2,5-dione (CAS 6252-98-8) is a high-purity analytical reference standard with the molecular formula C11H10N2O2 and a molecular weight of 202.21 g/mol.
2’,3’-Dihydrospiro[imidazolidine-4,1’-indene]-2,5-dione (C11H10N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
