Description Application This product is Informer compound X18 of the Aryl halide chemistry informer library developed by chemists at Merck and Co, which contains 18 drug-like molecules representative of those encountered in complex synthesis. By screening a new reaction against the Informer Library, chemists can directly compare and analyse a reaction′s successes and shortcomings among different methods and various research teams. It may also be used to facilitate deeper method development for performance or utility. Caution Not fully tested.
