Pharmaceutical purification processes are among the most energy–intensive operations in the chemical industry and involve substantial consumption of organic solvents. In recent years, organic solvent nanofiltration (OSN) membranes have attracted significant attention because of their potential to enhance these processes in terms of continuous operation, improved efficiency, and scalability. This paper introduces the development of OSN membranes within the Toyobo Group, outlines their efforts toward applications in the purification of medium–sized pharmaceutical molecules, and discusses future perspectives.
