Biotage PathFinder microwave reactions database
Biotage PathFinder provides direct access to years of experience in microwave synthesis
All content has been developed on Biotage microwave synthesis systems, making these methods highly reproducible. PathFinder also includes other valuable tools, such as the “Ask-a-Chemist” feature where chemists can have a dialog about microwave synthesis methods directly with an experienced Biotage chemist. Additional features include a gas pressure calculator and the PathFinder Cookbook.

Time prediction
Most times, reactions proceed faster using microwave synthesis simply because they are conducted at higher temperatures. When you set up experiments, the Initiator Wizard can provide help with prediction calculations. The built-in chart provides a way to estimate the time needed to run a reaction at a different temperature than reported. Based on the Arrhenius equation, it uses the coarse rule of thumb that a ten-degree increase in reaction temperature doubles the reaction speed. For example, if your reaction took four hours at 140 °C , it will take approximately two hours at 150 °C.
