TCP (Tritylchloride-Polystyrene) resins show higher stability compared to trityl resins for two reasons.
Due to the carboxyamidomethyl fragment the trityl linker is being pushed further away from the polystyrene matrix compared to conventional trityl resins and gives peptides more flexibility and stability. Furthermore, the carboxyamidomethyl fragment is an electron withdrawing moiety, hence the ester bond between trityl carbon and first amino acid becomes stronger.
