Mal-PEG4-t-butyl ester is a PEG linker that is commonly used in pegylation, a process of attaching polyethylene glycol (PEG) to molecules. It is a heterobifunctional PEG derivative, with one end containing a maleimide group and the other end terminated with a t-butyl ester. This versatile compound allows for specific and controlled conjugation of biomolecules, proteins, peptides, or drugs to PEG products. The maleimide group reacts selectively with thiol groups on target molecules, forming stable covalent bonds. The t-butyl ester can be easily cleaved under mild conditions to expose the maleimide group for further conjugation reactions. Mal-PEG4-t-butyl ester offers researchers a valuable tool for drug delivery systems, protein engineering, and other applications requiring site-specific modification.
