Chemical Structure
Description
The molecular framework of (2S,3S)-2-(4-Ethoxyphenyl)-1-ethyl-6-oxopiperidine-3-carboxylic Acid (C16H21NO4) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
(2S,3S)-2-(4-Ethoxyphenyl)-1-ethyl-6-oxopiperidine-3-carboxylic Acid (CAS 1391392-70-3), molecular formula C16H21NO4 and molecular weight 291.34 g/mol, is a CATO reference standard with documented purity and traceability.
