The molecular framework of (3R,4S,5R)-4-Hydroxy-5-[(1S)-1-hydroxy-2-methylpropyl]-3-methyl-2-pyrrolidinone-5-carboxylic Acid (C10H17NO5) 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.
(3R,4S,5R)-4-Hydroxy-5-[(1S)-1-hydroxy-2-methylpropyl]-3-methyl-2-pyrrolidinone-5-carboxylic Acid (CAS 145451-97-4) is a high-purity analytical reference standard with the molecular formula C10H17NO5 and a molecular weight of 231.25 g/mol.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
