I. [Product Description]
OPSS-PEG-leucine is a multifunctional organic intermediate with both pharmaceutical intermediate and polymer material modification functions. The o-pyridyl disulfide bond (OPSS) in its molecule enables efficient thiol coupling reactions, and the leucine residue confers specific recognition potential. Combining adjustable PEG chains, it can precisely control the balance of hydrophilicity and hydrophobicity, making it suitable for biological coupling and the construction of catalytic systems.
