Properties

Description

N-(Mal-PEG8-carbonyl)-N-bis(PEG8-t-butyl ester) is a branched PEG linker featuring a maleimide group, a carbonyl functional group, and two t-butyl-protected esters. The maleimide group reacts selectively with thiol groups to form stable covalent bonds, while the t-butyl esters can be deprotected under acidic conditions to expose carboxylic acids. The PEG8 spacers enhance solubility and hydrophilicity in aqueous media.
