I. [Product Introduction]
Estrogen-PEG-Mal is a high-purity organic intermediate that enables precise thiol coupling through maleimide groups, combining the targeting ability of estrogen ligands with the steric hindrance effect of PEG chains. This compound can be used as a pharmaceutical intermediate for constructing functional molecular carriers or as an amphiphilic linking unit in catalytic systems, significantly enhancing the water solubility and biocompatibility of the complexes.
