Used in drug delivery systems to enhance the solubility and stability of therapeutic compounds. It serves as a linker in bioconjugation, enabling the attachment of drugs to targeting molecules like antibodies or peptides. Applied in the development of prodrugs, where it facilitates controlled release of active agents at targeted sites. Also utilized in nanotechnology for creating biocompatible nanoparticles for cancer therapy and diagnostics. Its hydrophilic properties improve the pharmacokinetics of hydrophobic drugs, making them more effective in vivo.
