Applications of 31543-75-6
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Key intermediate for synthesizing antifungal agents (e.g., terbinafine analogues) | Carbon–carbon bond formation via Grignard reagent coupling or catalytic cross-coupling following bromination |
| Agrochemical Intermediates | Used in the preparation of brominated benzoic acid–based herbicides and insecticides | Multi-step synthesis involving nitration, reduction, diazotization, and bromination—or direct bromination followed by functional group introduction |
| Organic Synthesis | Multifunctional aromatic building block for constructing asymmetric dibrominated arenes | Lithium–halogen exchange followed by reaction with electrophiles (e.g., aldehydes, ketones, CO₂), or participation in palladium-catalyzed coupling reactions (e.g., Suzuki, Heck) |
| Materials Science | Used to synthesize precursors for brominated flame retardants and liquid crystal monomers | Condensation polymerization with bisphenols to produce brominated polycarbonates, or condensation with cyanophenols to prepare mesogenic liquid crystal molecules |
