Patent number: 12269844Abstract: The present invention provides improved processes for purifying semaglutide or liraglutide. Semaglutide or liraglutide is purified via two sequential RP-HPLC purifications followed by a salt-exchange step, where a pH is kept constant in the first and second purification steps. In particular, the processes utilize a halogenated solvent in a sample preparation step, which provides better solubility and an environment suitable for decarboxylation for crude semaglutide or liraglutide prior to a RP-HPLC purification.Type: GrantFiled: February 8, 2021Date of Patent: April 8, 2025Assignee: ScinoPharm Taiwan, Ltd.Inventors: Ming-Chih Wu, Tsung-Yu Hsiao
