Properties

Description

Bromoacetamido-PEG4-acid is a PEG linker comprising a bromide group and a terminal carboxylic acid. Its hydrophilic PEG spacer enhances solubility in aqueous media. With the bromide (Br) acting as an excellent leaving group for nucleophilic substitution reactions, the terminal carboxylic acid can form stable amide bonds with primary amine groups in the presence of activators such as EDC or HATU.
