Properties

Description

3,4-Dibromo-Mal-PEG8-Amine is a PEG linker featuring a site-specific amine group and a dibromomaleimide group. The dibromomaleimide moiety provides two reactive points, enabling dual substitution via the two bromine atoms. The amine group is highly reactive with carboxylic acids, activated NHS esters, carbonyl compounds, facilitating the formation of stable covalent bonds. The PEG spacer (8 ethylene glycol units) enhances water solubility, making this compound highly soluble in aqueous media.
