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.
CATO supplies rac-(3R,4R)-1-benzyl-4-cyclohexylpyrrolidine-3-carboxylic acid (CAS 2044706-19-4), a certified reference material (molecular formula C18H25NO2, MW 287.40 g/mol) for analytical method development and quality control.
rac-(3R,4R)-1-benzyl-4-cyclohexylpyrrolidine-3-carboxylic acid (C18H25NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), rac-(3R,4R)-1-benzyl-4-cyclohexylpyrrolidine-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.
