Chemical Structure
Description
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.
rac-(3R,4R)-pyrrolidine-3,4-dicarboxylic acid hydrochloride (CAS 1909288-35-2) is a high-purity analytical reference standard with the molecular formula C6H9NO4HCl and a molecular weight of 195.60 g/mol.
The molecular framework of rac-(3R,4R)-pyrrolidine-3,4-dicarboxylic acid hydrochloride (C6H9NO4HCl) 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.
As a certified reference material (CRM), rac-(3R,4R)-pyrrolidine-3,4-dicarboxylic acid hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
