Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2S,5R)-pyrrolidine-2,5-dicarboxylic acid.
(2S,5R)-pyrrolidine-2,5-dicarboxylic acid (CAS 35634-41-4), molecular formula C6H9NO4 and molecular weight 159.14 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (2S,5R)-pyrrolidine-2,5-dicarboxylic acid is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 159.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
CATO manufactures (2S,5R)-pyrrolidine-2,5-dicarboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
