Chemical Structure
Description
The molecular framework of (2R,5S)-5-Hydroxypiperidine-2-carboxylic acid hydrochloride (C6H11NO3HCl) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO supplies (2R,5S)-5-Hydroxypiperidine-2-carboxylic acid hydrochloride (CAS 138662-59-6), a certified reference material (molecular formula C6H11NO3HCl, MW 181.62 g/mol) for analytical method development and quality control.
