Chiral synthesis
WebGrinding solid materials in a ball mill speeds up sublimation and can be used to separate chiral molecules in a simple way. The finding by scientists in Germany who developed a way to monitor the process in real time using NMR spectroscopy, could open up new possibilities in pharmaceutical research and medicinal chemistry. WebChiral Synthesis Customization, Flexibility, and Expertise Enantio-selective synthesis provides access to biologically active small molecules within the pharmaceutical industry. We offer custom synthesis of chiral molecules through separation of racemic material as well as modern asymmetric synthesis.
