SPDP-PEG-azide is a chemical compound that belongs to the class of polyethylene glycol (PEG) derivatives. This compound consists of three functional groups: N-succinimidyl-3-(2-pyridyldithio) propionate (SPDP), PEG, and azide. SPDP is a heterobifunctional crosslinker that can react with primary amines and thiol groups, while the azide functional group (-N3) is known for its ability to react with alkyne groups via click chemistry.

In the field of pharmaceutical research and development, SPDP-PEG-azide has found widespread use in the development of drug delivery systems and bioconjugation strategies. Its unique chemical properties allow for the covalent attachment of drugs, peptides, and proteins to a PEG chain via SPDP, and subsequent conjugation to biomolecules via click chemistry.

This versatile compound has been employed in the development of novel drug delivery systems, such as micelles, liposomes, and nanoparticles. Its ability to target specific biomolecules through click chemistry has been used for targeted drug delivery and imaging applications.
