This document discusses two case studies using kinetic modeling and DynoChem software to improve pharmaceutical synthesis processes. In the first case, three mechanisms were evaluated to predict an anti-bacterial reaction and reduce impurities. Mechanism 3 best fit the data and parameters from it improved yield. The second case developed a kinetic model for an API synthesis to minimize impurities and maximize yield through simulation and optimization. Process changes based on the mechanisms reduced reaction time and improved purity and yield. Overall, kinetic modeling with DynoChem helped analyze reaction mechanisms and improve two industrial synthesis processes.
