This compound is primarily used in the field of bioconjugation and drug delivery systems. It serves as a linker or spacer molecule, facilitating the attachment of drugs, proteins, or other biomolecules to larger carriers or surfaces. The THP (tetrahydropyranyl) group acts as a protective moiety, which can be selectively removed under mild acidic conditions, allowing for controlled release or activation of the attached molecule. The PEG (polyethylene glycol) segment enhances solubility, reduces immunogenicity, and improves the stability of the conjugated molecules in biological environments. This makes it particularly valuable in the development of targeted therapies, such as antibody-drug conjugates (ADCs), where precise delivery and release of therapeutic agents are critical. Additionally, it is employed in the modification of peptides and proteins to enhance their pharmacokinetic properties.
