The chemical is widely used in the field of bioconjugation and drug delivery systems. It serves as a crucial linker molecule, enabling the attachment of therapeutic agents to polymers or nanoparticles, thereby enhancing their stability and targeting efficiency. Its application is particularly significant in the development of antibody-drug conjugates (ADCs), where it helps in connecting cytotoxic drugs to antibodies, ensuring precise delivery to cancer cells while minimizing damage to healthy tissues. Additionally, it is employed in the synthesis of PEGylated compounds, which are essential for improving the pharmacokinetics and bioavailability of various drugs. Its role in creating biocompatible and water-soluble materials also makes it valuable in biomedical research and therapeutic formulations.
