I. [Product Description]
SS-PEG-leucine (Disulfide-Polyethylene Glycol-Leucine) is a multifunctional organic intermediate that combines the dynamic reversible properties of disulfide bonds with the hydrophilic modification ability of PEG chains. The leucine residues in its structure can provide directional coupling sites, making it suitable for the synthesis of pharmaceutical intermediates, the modification of polymer materials, and the functional design of catalytic carriers. It shows significant application potential in controlled release systems.
