CAS号 Hill配方 摩尔质量 143824-78-6 C₃₁H₃₀N₂O₆ 526.59 g/mol 描述 概述 "The use of this N-in-Boc protected derivative overcomes most of the problems associated with the preparation of Trp containing-peptides by Fmoc SPPS [1]. Cleavage with TFA generates an N-in-carboxy indole which protects the Trp from alkylation [1, 2, 3] and sulfonation [1, 4, 5, 6, 7]. The N-in-carboxy group is removed under aqueous conditions during normal work-up of the peptide.
The product number for this product was previously 04-12-1103.
