Route Scouting

Fast Delivery:  In early development, speed of delivery is the thumb rule. With accumulated chemistry capabilities and availability of diverse building blocks, our motivated and experienced chemists are able to work out innovative routes with high efficiency.

Optimal Route Scouting: To control the risk of changing route in late development, and secure a reliable supply throughout the whole development lifecycle, the team takes safety, efficiency, purity, cost, ease of scale-up, security of raw material supply, and impact on environment into consideration, and aim to design an optimal, fit-to-purpose route for customers' projects. 

Process Development, Optimization and Validation

•  Robust and phase appropriate process development
