Background information

The side-chain Mtt group can be selectively removed with 1% TFA in DCM [1, 2, 3] or DCM/HFIP/TFE/TES (6.5:2:1:0.5) [4], making this an excellent derivative for the synthesis of branched peptides, peptides modified at the lysine side-chain [5,6], for the construction of templates and multifunctionalized resins for combinatorial synthesis.

The product number for this product was previously 04-12-1137.
