Chemical Structure
Description
The molecular framework of (3S,4R)-1-[(tert-Butoxy)carbonyl]-4-{[(9H-fluoren-9-ylmethoxy)carbonyl]amino}pyrrolidine-3-carboxylic acid (C25H28N2O6) 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 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).
(3S,4R)-1-[(tert-Butoxy)carbonyl]-4-{[(9H-fluoren-9-ylmethoxy)carbonyl]amino}pyrrolidine-3-carboxylic acid (CAS 346610-79-5) is a high-purity analytical reference standard with the molecular formula C25H28N2O6 and a molecular weight of 452.50 g/mol.
