3,4-Dibromo-Mal-PEG2-N-Boc（Cat No.:I015703）is a functionalized polyethylene glycol (PEG) linker tailored for precision bioconjugation and synthetic chemistry. It features a maleimide group for selective thiol coupling, a dibromo unit enabling versatile substitution or crosslinking, and a Boc-protected amine that can be deprotected under mild conditions for further derivatization. The PEG2 spacer provides hydrophilicity and flexible spacing while minimizing steric hindrance, enhancing solubility and reactivity in both aqueous and organic media. This reagent is valuable in protein–drug conjugates, advanced biomaterials, and modular chemical synthesis.
