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 (3R,4R)-1-benzyl-3,4-difluoropyrrolidine.
(3R,4R)-1-benzyl-3,4-difluoropyrrolidine (CAS 2055174-55-3), molecular formula C11H13F2N and molecular weight 197.22 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H13F2N, (3R,4R)-1-benzyl-3,4-difluoropyrrolidine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 197.22 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.
