Fmoc-Ala-Ser(Psi(Me,Me)pro)-OH is a peroxide with an amine and a terminal carboxylic acid. The Fmoc group can be deprotected under alkaline conditions to obtain a free amine, which can be used as a free radical initiator for the synthesis of polymers such as polypropylene. . Phenoxy groups have been shown to catalyze hydrogen peroxide to form free radicals, and terminal carboxylic acids can react with primary amine groups in the presence of activators such as EDC or HATU to form stable amide bonds. Fmoc-Ala-Ser(Psi(Me,Me)pro)-OH is chemically stable and does not react with oxygen or light.
