I. [Product Description]
OPSS-PEG-Protected Amines (FMOC, tBOC) is a multifunctional organic intermediate that combines the directional coupling ability of o-pyridyldisulfide (OPSS) with the biocompatibility of the PEG chain. Meanwhile, it enables efficient and controllable modification of amino groups through FMOC/tBOC protecting groups. This product is suitable for the synthesis of pharmaceutical intermediates, the modification of polymer materials, and as a catalyst or ligand for bioconjugation reactions. It features precise molecular weight control and high batch-to-batch stability.
