Used as a peptide-based reagent in pharmaceutical research, particularly in the development of targeted therapies. Its primary application lies in bioconjugation processes, where it serves as a building block for modifying biomolecules to enhance stability, solubility, or binding affinity. Commonly employed in the synthesis of peptide-drug conjugates for oncology applications, it enables selective delivery of therapeutic agents to cancer cells. Also utilized in diagnostic imaging probes due to its ability to link imaging moieties to targeting peptides. Its trifluoroacetate form improves solubility in aqueous and organic solvents, facilitating handling in automated peptide synthesizers and high-throughput screening setups.
