I. [Product Description]
OPSS-PEG-phosphoric acid is a multifunctional organic intermediate containing ortho-pyridyl disulfide bonds, polyethylene glycol chains, and phosphate groups. It combines high-efficiency coupling ability with biocompatibility characteristics. As a pharmaceutical intermediate, it is widely used in the field of bioconjugation. Its thiol-pyridyl disulfide exchange reaction characteristic makes it a precisely controllable molecular connection tool, and the phosphate group provides additional hydrophilicity and reaction sites. It is suitable for catalytic systems requiring directional coupling, such as protein modification and nanocarrier construction.
