I. [Product Description]
OPSS-PEG-VA is a multifunctional organic intermediate that combines the dynamic exchange characteristics of the ortho-pyridyl disulfide bond with the excellent biocompatibility of polyethylene glycol (PEG). It can serve as an efficient catalyst or a linking arm and is widely used in the construction of bioconjugation and targeted delivery systems. The valeric acid (VA) end group further enhances its compatibility with hydrophobic materials, making it suitable for the design and optimization of complex reaction systems.
