mPEG2-CH2COOH (CAS 16024-58-1) is a short-chain PEG derivative with a terminal carboxylic acid group. It is widely used as a PEG linker in bioconjugation, drug delivery research, and organic synthesis. The carboxyl group enables efficient coupling with amine-containing molecules after activation, while the PEG spacer improves water solubility. It can also be used in adhesive compositions for dental applications.
