Properties

Description

3,4-Dibromo-Mal-PEG4-acid is a specialized PEG linker featuring a dibromomaleimide group and a terminal carboxylic acid. The dibromomaleimide provides two points of substitution via the bromine atoms, enabling versatile functionalization. The carboxylic acid group reacts with primary amines in the presence of activators like EDC or HATU to form stable amide bonds. The PEG4 spacer enhances solubility and hydrophilicity in aqueous environments.
