Process for the one-stage resalting and purification of oligopeptides |
| abstract |
The present invention relates to a process for the one-stage resalting and purification of oligopeptides. Oligopeptides are often not formed directly as acetates when synthesised. Acetate salts of oligopeptides are however desirable as bulk-active material for medical and formulation reasons. Processes known from the prior art have hitherto involved two separate steps or pyridine-containing solvents. According to the invention the resalting and purification can be combined in one step or the use of pyridine as solvent can be avoided, if the oligopeptide in the form of its chloride salt is purified with an acetate-containing solvent by liquid chromatography methods. |
