This chemical is primarily utilized in the field of organic synthesis and pharmaceutical research. It serves as a key intermediate in the development of complex molecules, particularly in the synthesis of polyethylene glycol (PEG) derivatives. These derivatives are widely used to modify the properties of drugs, such as improving solubility, stability, and bioavailability. Additionally, it finds application in the preparation of prodrugs, where it acts as a linker to attach therapeutic agents to carriers, enabling targeted drug delivery. Its methanesulfonate group also makes it a valuable reagent in alkylation reactions, contributing to the creation of various biologically active compounds.
