Applications of 5978-22-3
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Protecting reagent for lysine residues in peptide synthesis | Used as a side-chain protecting group in Fmoc-based solid-phase peptide synthesis (SPPS) to introduce protected lysine units; the hydrochloride salt form facilitates dissolution and coupling reactions |
| Biochemical Research | Modification intermediate for protein/peptide structure and function studies | Provides orthogonal protection in liquid-phase peptide synthesis and fragment condensation; benzyloxycarbonyl (Cbz) and tert-butyl (Boc) groups enable selective deprotection of the α-amino and side-chain amino groups |
| Fine Chemicals | Key synthetic intermediate for chiral drugs and peptide-based APIs | Cbz group removed via catalytic hydrogenolysis or HBr/acetic acid, followed by tert-butyl ester removal with TFA to liberate the free lysine side chain; the hydrochloride salt form enhances crystallinity and storage stability |
