Mal-PEG-trimethylammonium chloride is a chemical compound that belongs to the class of polyethylene glycol (PEG) derivatives. This compound contains a quaternary ammonium group (-N+(CH3)3) attached to the PEG chain via a maleimide functional group.

Mal-PEG-trimethylammonium chloride has been extensively utilized in the development of novel drug delivery systems, such as gene delivery vectors and protein-based therapeutics. Its cationic nature allows for the electrostatic interaction with negatively charged biomolecules, facilitating their delivery to target cells or tissues. The resulting conjugates exhibit improved cellular uptake and bioavailability, leading to enhanced therapeutic efficacy and reduced toxicity.

Mal-PEG-trimethylammonium chloride has also been employed as a surface modifier in various biomedical applications. For example, it can be immobilized onto the surface of nanoparticles or medical devices to improve their stability, biocompatibility, and cellular uptake.
