Chemical Structure

O1-tert-butyl O2-methyl (2S,4R,5S)-4-fluoro-5-methyl-pyrrolidine-1,2-dicarboxylate CAS 1984825-19-5 chemical structure

Description

The molecular framework of O1-tert-butyl O2-methyl (2S,4R,5S)-4-fluoro-5-methyl-pyrrolidine-1,2-dicarboxylate (C12H20FNO4) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
