1 Advancer Kilobatch kilogram scale-up of all microwave chemistry
2 Background MW reactions are become more common place in Discovery / Med Chem MW reactions can be higher yield / higher purity MW reactions are typically 10 to 1000 times faster MW can enable some chemistries that are impossible through traditional heating methods Many MW reactions (50-75%) are heterogeneous at either start, completion, or both MW difficulty at preclinical scale For delivery of first 100g and kgs, the smallest investment in re-optimization is best Time and Money spent for re-optimization will not bear fruit in large percentage of projects Fail early, fail cheaply No commercially available product that can scale all (or even most) chemistries to kg scale without a great deal of time (money) investment to tweak / optimize chemistry
3 Scale-up needs Speed fast & reproducible results Scalability no time for re-optimizations Support for all types of chemistry Safety
4 Choices Larger batch Make everything bigger Automated continuous batch Run many times at the same scale Flow through Perform the reaction in a continuous flow
5 Choices Larger batch Make everything bigger + no re-optimization adoptable to all chemistry quick turnaround - Safety concerns limited scale sufficient power stirring scalability?
6 Choices Automated continuous batch Run many times at the same scale + no re-optimization adoptable to all chemistry safe limitless scale sufficient power stirring - Turnaround time amendable for automation? reproducibility?
7 Choices Flow through Perform the reaction in a continuous flow + safe limitless scale - Turnaround time re-optimization required Not adoptable to all chemistry amendable for automation? reproducibility?
8 Choices Larger batch Make everything bigger Automated continuous batch Run many times at the same scale Flow through Perform the reaction in a continuous flow
