NH2-PEG4-COOH.HCl is PEG linker termenated with a primary amine group (NH2) and a carboxylic acid group (COOH). The amine group allows for specific and efficient conjugation reactions with carboxylic acid-functionalized molecules or surfaces, facilitating the attachment of biomolecules or other ligands to the PEG chain. The hydrochloride salt form (HCl) of NH2-PEG4-COOH is often utilized for enhanced stability and handling convenience in aqueous solutions.

NH2-PEG4-COOH.HCl can be used in optical imaging of integrin αvβ3 expression with near-infrared fluorescent RGD dimer with tetra(ethylene glycol) linkers. Integrin αvβ3 plays great roles in tumor angiogenesis, invasion, and metastasis.
