Mal-PEG3-OH (Mal-PEG3-alcohol, CAS 146551-23-7) is a versatile linker featuring a maleimide group and a hydroxyl group. The PEG spacer enhances the solubility of the compound in aqueous solutions. The hydroxyl group can be easily modified to introduce other reactive functional groups. The maleimide group selectively reacts with thiol groups, forming a stable covalent C-S bond, making it ideal for bioconjugation with thiol-containing molecules.
