Used as an intermediate in organic synthesis, particularly in the preparation of functionalized peptides and polymers. It serves as a protected aminoalkyl linker in solid-phase peptide synthesis, enabling the attachment of molecules to resins or other scaffolds through its tosylate group. The Boc-protected amine allows for controlled deprotection under acidic conditions, making it valuable in stepwise synthesis. Also employed in the development of bioconjugates and prodrugs where selective reactivity and stability are required.
