Applications of 92122-45-7
| Industry | Application | Process |
|---|---|---|
| Biopharmaceuticals | Bifunctional protecting reagent for lysine residues in solid-phase peptide synthesis (SPPS), enabling selective introduction of side-chain protecting groups | In Fmoc-based SPPS, the α-amino group is protected with Fmoc and the ε-amino group with Boc to achieve orthogonal deprotection; the Fmoc group is removed under mild basic conditions (e.g., piperidine), while the Boc group is selectively cleaved under acidic conditions (e.g., TFA) |
| Pharmaceutical R&D | Key building block for constructing lysine-containing therapeutic peptides, cyclic peptides, and conjugates (e.g., ADC linker-payload intermediates) | Used as a chiral non-natural amino acid monomer in automated peptide synthesizers; activated with DIC/HOBt or HATU prior to coupling with resin-bound peptide chains |
| Biomaterials | Preparation of functional, biocompatible hydrogels or peptide scaffolds, leveraging lysine side chains for crosslinking or modification | Boc protection of the ε-amino group suppresses side reactions; after deprotection, functional groups such as NHS esters or maleimides are introduced to enable covalent crosslinking or targeted modification |
