Used primarily in biochemical and pharmaceutical research as a complex peptide-based scaffold or intermediate. Its highly functionalized macrocyclic structure with multiple amine and amide groups makes it suitable for applications in drug delivery systems, molecular recognition, and as a building block in the synthesis of bioactive compounds. Often employed in studies involving protein mimetics or enzyme inhibition due to its conformational rigidity and selective binding capabilities. Also utilized in the development of targeted therapeutics, especially where enhanced stability and specificity are required. The trifluoroacetate salt form improves solubility and handling in aqueous and polar organic solvents, facilitating its use in biological assays and conjugation reactions.
