I. [Product Description]
Vitamin E-PEG-Mal is a multifunctional organic intermediate/ pharmaceutical intermediate. Through the antioxidant properties of vitamin E, the high-efficiency thiol reactivity of maleimide groups, and the hydrophilicity of PEG chains, it achieves precise molecular coupling and enhanced stability. It can be used as a biocompatible linker or catalyst carrier, and is widely used in material surface modification and functional development.
