I. [Product Introduction]
OPSS-PEG-ALK is a multifunctional organic intermediate that combines high-efficiency catalytic activity with precise molecular design capabilities. It is widely used in the fields of bioconjugation reactions and surface functionalization of materials. The ortho-pyridyl disulfide (OPSS) group in its structure enables specific thiol conjugation, the alkyne (ALK) terminus supports click chemistry reactions, and the PEG chain provides excellent water solubility and molecular tunability. It is an ideal choice for constructing functionalized nanocarriers.
