Late-stage functionalisation: a unique perspective from a research scientist turned patent attorney
Late-stage functionalisation has emerged as a valuable enabling tool within the arsenal of a medicinal chemist. As newer synthetic methods become developed for the generation of small molecules, so too has the chemical space that medicinal chemists will have access to. Of course, these methods are valuable to the R&D team – but did you know that late-stage functionalisation will also likely have an impact on the IP profession?

Get the F out of my chemical: tackling PFAS contamination
Per- and polyfluoroalkyl substances (PFAS) contain multiple carbon-fluorine bonds. These bonds give rise to desirable properties, e.g. tolerance to high temperatures, which has led to widespread use of PFAS. Extensive use of PFAS has resulted in contamination of water and soil with these chemicals, but what can be done to combat this?
