Properties

Description

4-(2,5-Dioxo-2H-pyrrol-1(5H)-yl)butanoic acid is a chemical compound containing a maleimide group and a terminal carboxylic acid. The maleimide group is reactive with thiol groups, forming stable covalent bonds, making it ideal for thiol-specific conjugations. The terminal carboxylic acid group can react with primary amines in the presence of activators like EDC or HATU, enabling the formation of stable amide bonds. This compound offers both thiol- and amine-reactive functionalities, ideal for creating biomolecule conjugates.
