Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 195.60 g/mol gives (3r,4r)-Pyrrolidine-3,4-dicarboxylic acid hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (3r,4r)-Pyrrolidine-3,4-dicarboxylic acid hydrochloride (CAS 1807938-89-1), a certified reference material (molecular formula C6H9NO4HCl, MW 195.60 g/mol) for analytical method development and quality control.
The molecular framework of (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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (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.
