This chemical is primarily used in bioconjugation and drug delivery systems. Its structure allows it to act as a linker, connecting therapeutic molecules to targeting agents or carriers, enhancing the stability and solubility of drugs. It is particularly useful in the development of antibody-drug conjugates (ADCs), where it helps in attaching cytotoxic drugs to antibodies for targeted cancer therapy. Additionally, it finds application in modifying proteins and peptides to improve their pharmacokinetic properties, such as extending their circulation time in the body. The THP (tetrahydropyran) group provides protection during synthesis, ensuring selective reactions in complex molecular assemblies.
