PEG-Ms(PEG-mesyl) is a chemical compound that belongs to the class of polyethylene glycol (PEG) derivatives. This compound contains a mesyl functional group (-SO3CH3) attached to the terminal carbon atom of a PEG chain.

PEG-mesyl has been extensively utilized in the development of novel drug delivery systems, such as prodrugs, polymer conjugates, and dendrimers. Its unique chemical properties allow for the covalent attachment of therapeutic agents, such as drugs and peptides, to the PEG chain via mesylate ester bonds. The resulting conjugates exhibit improved solubility, stability, and bioavailability, leading to enhanced therapeutic efficacy and reduced toxicity.

In addition to its use in drug delivery systems, PEG-mesyl has also been employed as a linker in the synthesis of complex organic molecules, such as natural products and analogs. The mesyl group can be used to selectively protect hydroxyl or amine groups during synthetic transformations, allowing for the targeted modification of specific functional groups without affecting the overall molecular structure.
