CAS号 Hill配方 摩尔质量 103213-32-7 C₃₇H₃₁NO₄S 585.72 g/mol 描述 概述 "The standard derivative for Fmoc SPPS of peptides containing Cys [1]. The Trt group is removed with 95% TFA containing 1-5% TIS. Ideally, this derivative should be introduced using the symmetrical anhydride or DIPCDI/HOBt activation [2,3] to minimize enantiomerization. If activation with uronium or phosphonium reagents, such as HBTU or PyBOP®, is to be employed, it is strongly recommended that collidine is used as the base [4], as this has been shown to significantly reduce loss of optical integrity during coupling.
