Research & Development

At Raybow, our experienced and innovative R&D team is focused on process development for our customer projects. This includes early preclinical stage and clinical stage, all the way to commercial stage. Our process chemists, analytical chemists and process engineers work together in their efforts to develop efficient processes that optimize manufacturing efficiency, product quality, process safety, COGS, supply chain and environmental sustainability. We strive to meet and often exceed our customer requirements.

Raybow's R&D team consists of synthetic and analytical chemists. We have nearly 300 high-level R&D professionals. The team is led by top international PhD scientists. We have successfully delivered over 450 R&D services projects in collaboration with innovative companies from around the world. This includes many NCE-projects, submitted to Chinese, EU and US regulatory authorities.
