"Chemistry's Workhorse Separates Mirror-Image Molecules"

Chemists have demonstrated the use of mass spectrometry to separate chiral molecules, which exist as mirror-image structures with different properties. This breakthrough could streamline the laborious process of separating enantiomers, crucial in drug discovery, by allowing for quick determination of enantiomeric excess and confirmation of molecular structures. The technique, described in Science, has the potential to simplify and expedite the preparation of pure samples of enantiomers in larger quantities, with implications for drug design and discovery.
