Industrial Applications of 4-BROMO-DL-PHENYLALANINE
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Non-natural amino acid building block for synthesizing peptide-based drugs | Introduction of p-bromophenylalanine residues in solid-phase peptide synthesis (SPPS) for structure–activity relationship studies or as sites for subsequent coupling reactions (e.g., Suzuki coupling) |
| Biochemistry | Protein engineering and probe construction | Site-specific modification via the bromine atom on the aromatic ring—e.g., palladium-catalyzed cross-coupling to introduce fluorophores, biotin, or other functional groups |
| Organic Synthesis | Intermediate for synthesizing complex aromatic compounds | Participation as an aryl halide in transition metal-catalyzed cross-coupling reactions—including Suzuki, Heck, and Sonogashira—to construct C–C or C–heteroatom bonds |
| Agrochemical R&D | Structural motif for potential active molecules | Used in the design and synthesis of novel pesticide lead compounds with targeted biological activity |
Manufacturing Quality Control of 4-BROMO-DL-PHENYLALANINE
| Detection Item | Common Analytical Method | Method Overview |
