Process: The importance of safety is obvious. The research and development of specialty drug substances (especially high-barrier generic drug substance drugs) usually need to avoid the original process patents, and some chemicals are developed because of the complex structure or the harsh synthetic conditions The synthetic route is more difficult, so the importance of process design capabilities of API companies is becoming more important.
