Chemical Structure
Description
The molecular framework of methyl (2R)-azetidine-2-carboxylate hydrochloride (C5H9NO2HCl) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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.
methyl (2R)-azetidine-2-carboxylate hydrochloride (CAS 647854-63-5) is a high-purity analytical reference standard with the molecular formula C5H9NO2HCl and a molecular weight of 151.59 g/mol.
