Applications of 71229-85-1
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Key intermediate in the synthesis of the antifungal drug voriconazole | Condensed with 2,4-difluorobenzaldehyde under basic conditions, followed by cyclization and oxidation to construct the triazole side chain |
| Pesticide R&D | Structural modification unit for novel insecticides and fungicides | Serves as a brominated precursor for pyrazole heterocyclic scaffolds, enabling introduction of aryl or alkenyl substituents via Suzuki or Heck coupling reactions |
| Organic Synthesis | Substrate for metal-catalyzed cross-coupling reactions (e.g., Suzuki, Stille, Negishi) | Undergoes C–C bond coupling with boronic acids, stannanes, or organozinc reagents in the presence of palladium catalysts (e.g., Pd(PPh₃)₄ or Pd(dppf)Cl₂) |
