Chemical Structure
Description
The molecular framework of tert-Butyl 4-(2-methoxy-2-oxoethyl)-3-oxopiperidine-1-carboxylate (C13H21NO5) is characterized by a nitrogen-containing heterocyclic scaffold, 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.
tert-Butyl 4-(2-methoxy-2-oxoethyl)-3-oxopiperidine-1-carboxylate (CAS 1159983-58-0) is a high-purity analytical reference standard with the molecular formula C13H21NO5 and a molecular weight of 271.31 g/mol.
