use | synthesis of ubenimex intermediates and polypeptide protectants. It is widely used in the condensation reaction of polypeptides with carbodiimide condensers, which can significantly reduce the racemization ratio, and is also used to prevent the production of racemization during the condensation of polypeptide fragments. Used as a pharmaceutical intermediate, metal surface treatment agent |
