This is a question being asked of my colleagues and me more and more frequently, especially in pharma accounts. Why? Well, you are familiar with the adage – Time is Money, right. Well this really applies to them. A new molecular entity (NME) created as a pharmaceutical can take up to a decade and a billion dollars to bring to market. Granted, the biggest costs are in the clinical trials but the synthetic route and the time to discover and make the compound – and purify it – plays a major role within drug discovery and development. This timeline is not helped by the ever increasingly difficult-to-synthesize compounds being investigated as drug candidates today.
With that in mind, this post focuses on ways to speed the purification process without sacrificing purity and yield.
