This chemical is widely used in the field of bioconjugation and drug delivery systems. It serves as a versatile linker molecule, enabling the attachment of various therapeutic agents, such as drugs or imaging probes, to biomolecules like antibodies or peptides. The THP (tetrahydropyran) group provides a protective function, ensuring stability during synthesis or storage, while the PEG6 (polyethylene glycol) spacer enhances solubility and reduces immunogenicity. This makes it particularly useful in the development of targeted therapies, where precise delivery of active compounds to specific cells or tissues is required. Additionally, it is employed in the preparation of prodrugs, where the THP group can be selectively cleaved under specific conditions to release the active drug at the desired site. Its applications extend to research in antibody-drug conjugates (ADCs) and other advanced therapeutic modalities.
