I. [Product Description]
Mal-PEG-CH₂CH₂COOtBu is a multifunctional organic intermediate that combines the high reactivity of maleimide with the excellent water solubility and biocompatibility of polyethylene glycol (PEG). It is suitable for protein modification, nanomaterial synthesis, and bioconjugation reactions. Its tert-butoxycarbonyl (tBu) protecting group can effectively regulate the reaction selectivity and is a key material for the development of pharmaceutical intermediates and the construction of catalyst support systems.
