| uses | racemic inhibitors in polypeptide synthesis. It has been reported that its effect is better than N-hydroxysuccinimide (HOSu,NHS) In peptide synthesis, it is an effective reagent for connecting with DCC. This reagent can reduce racemization and inhibit N-acylurea. Generation, and obtain a high-yield peptide; the corresponding chloroformate can be used to introduce different types of amino protecting groups |
