Applications of 51186-58-4
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Chiral building block for peptide-based drug synthesis | Used as a protected aspartic acid derivative in solid-phase or solution-phase peptide synthesis; introduced via Fmoc/t-Boc strategies, with the α-amino group protected by tert-butoxycarbonyl (Boc) and the side-chain carboxyl group protected by a benzyl ester to enable selective deprotection and coupling reactions |
| Biochemical Research | Synthesis of custom aspartic acid-containing peptides for studying enzyme substrate specificity or protein structure–function relationships | Condensation performed using standard peptide coupling reagents (e.g., HBTU, DIC); Boc deprotection carried out under mild acidic conditions (e.g., TFA), and benzyl ester removal achieved via hydrogenolysis or strong acid treatment |
| Fine Chemicals | High-purity amino acid derivative intermediate for developing novel pharmaceutical intermediates or diagnostic reagents | Produced via asymmetric synthesis or resolution, followed by esterification and Boc protection; purified for subsequent construction of complex molecular frameworks |
