DL-2-Aminosuberic Acid is primarily used in peptide synthesis and biochemical research. It serves as a non-natural amino acid building block, enabling the creation of modified peptides with enhanced stability or altered properties. Its application extends to studying protein structure and function, particularly in investigating enzyme-substrate interactions or designing inhibitors. Additionally, it is utilized in the development of peptide-based drugs, where its unique structure can improve pharmacokinetics or bioavailability. In material science, it contributes to the design of novel biomaterials with specific functional characteristics.
