Chemical Structure
Description
Structurally, tert-Butyl 7-methoxy-2-oxospiro[indoline-3,3'-pyrrolidine]-1'-carboxylate (C17H22N2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 318.37 g/mol, it falls into the moderately-high-molecular-weight range. 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).
tert-Butyl 7-methoxy-2-oxospiro[indoline-3,3'-pyrrolidine]-1'-carboxylate (CAS 2089301-07-3) is a high-purity analytical reference standard with the molecular formula C17H22N2O4 and a molecular weight of 318.37 g/mol.
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.
