I. [Product Description]
tBOC-NH-PEG-Mal is a multifunctional organic intermediate. Its tert-butoxycarbonyl (tBOC) protecting group is connected to the maleimide active group through a polyethylene glycol (PEG) chain, combining chemical stability and controllable reactivity. As a pharmaceutical intermediate, it is widely used in bioconjugation, polymer material modification, and catalytic system construction. The hydrophilicity of the PEG chain can significantly improve the solubility and biocompatibility of the compound.
