PEG-SO2-PEG is a type of polyethylene glycol (PEG) derivative that contains two sulfonate functional groups (-SO2-) attached to either end of a PEG chain.

The sulfonate groups in PEG-SO2-PEG enable it to interact with other molecules through electrostatic interactions, making it useful in the development of drug delivery systems. PEG-SO2-PEG can be used to modify the surface of nanoparticles or liposomes to improve their stability and targeting capabilities. It can also be used to covalently attach therapeutic agents, such as proteins and peptides, to the PEG chain, resulting in enhanced drug efficacy and reduced toxicity.
