Bromoacetamido-PEG12-acid represents a PEG linker featuring a bromo group, which is a good leaving group for nucleophilic substitution reactions (e.g., thiol or amine), and carboxylic acid, which can react with primary amine groups in the presence of activators such as HATU. The PEG12 chain elevates the hydrophilicity of the molecule. Reagent grade, for research purpose.
