Chemical Structure
Description
(2R,4R)-4-phenylpyrrolidine-2-carboxylic acid (CAS 103290-41-1), molecular formula C11H13NO2 and molecular weight 191.23 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H13NO2, (2R,4R)-4-phenylpyrrolidine-2-carboxylic acid contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 191.23 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 (2R,4R)-4-phenylpyrrolidine-2-carboxylic 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.
