Chemical Structure
Description
The molecular framework of tert-Butyl 4-methoxy-2-oxospiro[indoline-3,3'-pyrrolidine]-1'-carboxylate (C17H22N2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
tert-Butyl 4-methoxy-2-oxospiro[indoline-3,3'-pyrrolidine]-1'-carboxylate (CAS 2089315-17-1) is a high-purity analytical reference standard with the molecular formula C17H22N2O4 and a molecular weight of 318.37 g/mol.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
