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 rac-(3R,4R)-1-benzyl-4-cyclopentylpyrrolidine-3-carboxylic acid.
rac-(3R,4R)-1-benzyl-4-cyclopentylpyrrolidine-3-carboxylic acid (CAS 2044705-92-0) is a high-purity analytical reference standard with the molecular formula C17H23NO2 and a molecular weight of 273.37 g/mol.
The molecular framework of rac-(3R,4R)-1-benzyl-4-cyclopentylpyrrolidine-3-carboxylic acid (C17H23NO2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), rac-(3R,4R)-1-benzyl-4-cyclopentylpyrrolidine-3-carboxylic acid 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.
