Streamlined Impurity Characterization Through Molecular Rotational Resonance (MRR) Spectroscopy for Isomer Discrimination

Summary

 Fluorinated quinoline and isoquinoline regioisomers can share the same molecular mass while having different structures, making them difficult to distinguish using traditional analytical workflows.

Molecular rotational resonance (MRR) overcomes this challenge by providing a structure-specific molecular fingerprint, enabling rapid and confident isomer identification.

Download the poster to see how MRR identified seven fluorinated quinoline and isoquinoline components within a mixture, reducing structural ambiguity and increasing confidence in pharmaceutical impurity characterization.
