Over the past 5 years or so the development of continuous flow electrochemical cells has made selective syntheses with high reactant-to-product conversions possible. These devices offer an easy access to electrochemical techniques which is driving its current re-assessment as a viable, attractive synthetic method. Discover more in this blog post.
My first introduction to practical flow chemistry was as a Research Chemist at Pfizer and my first thought was: “why on earth would I want to conduct my chemistry in tiny tubes?” A few years later I was the biggest advocate for it. This blog post explains why…
Let’s start with the basics and explain what flow chemistry actually is and talk a bit about why it’s so useful. Flow chemistry is the process of performing chemical reactions in a tube or pipe. Read on to learn more…
So why should your lab consider performing your chemistry using continuous flow chemistry techniques? Discover several reasons including faster and reactions, and accessing novel chemistries not possible in batch
