Chemical Structure

Methyl (1R,3S,4R)-3-{[(tert-butoxy)carbonyl]amino}-4-hydroxycyclopentane-1-carboxylate CAS 321744-23-4 chemical structure

Description

The molecular framework of Methyl (1R,3S,4R)-3-{[(tert-butoxy)carbonyl]amino}-4-hydroxycyclopentane-1-carboxylate (C12H21NO5) is characterized by an amino-acid-derived structure, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
