- Description
Br-PEG4-COOH is a PEG linker combining a bromide group with a terminal carboxylic acid. Its hydrophilic spacer supports aqueous solubility for bioconjugation work. The bromide acts as a leaving group in nucleophilic substitution, while the carboxylic acid can be coupled to primary amines using reagents such as EDC or HATU to form amide bonds. It is also known as Bromo-PEG4-acid.
