Used in bioconjugation and drug delivery systems, it serves as a linker molecule to attach therapeutic agents or targeting moieties to biomolecules. Its t-butyl ester group provides stability during synthesis, while the hydroxyl group allows for further functionalization. Commonly applied in the development of antibody-drug conjugates (ADCs) and peptide-based therapeutics, it enhances solubility and bioavailability of hydrophobic drugs. Additionally, it is utilized in polymer chemistry to modify surface properties of materials for biomedical applications.
