This chemical is primarily used in the synthesis of peptides and peptidomimetics, serving as a protected amino acid derivative. Its structure, featuring a tert-butoxycarbonyl (Boc) protecting group, makes it valuable in solid-phase peptide synthesis (SPPS) where selective deprotection is required. The compound is particularly useful in constructing complex peptide chains, as the Boc group can be removed under acidic conditions without affecting other functional groups. Additionally, its unsaturated side chain (pent-4-enoic acid) allows for further chemical modifications, such as cross-coupling reactions, enabling the creation of diverse peptide-based molecules. This makes it a versatile intermediate in pharmaceutical research, especially in the development of bioactive peptides and drug candidates.
