Description

Pyridine, 3-[(1E)-2-Bromoethenyl]- (9Ci) is a specialized brominated vinylpyridine derivative, serving as a high-value synthetic intermediate in advanced organic chemistry. Its core value lies in its unique molecular architecture, which combines a reactive bromoalkene moiety with a pyridine heterocycle, enabling precise functionalization and cross-coupling reactions. This compound is essential for researchers and process chemists in the pharmaceutical and agrochemical sectors developing novel active ingredients, as well as in materials science for creating functional polymers and ligands.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of complex drug candidates, particularly those requiring pyridine-based heterocycles for bioactivity.
• Agrochemical Synthesis: Used in the research and development of new pesticides and herbicides, where the bromovinyl group allows for efficient structural diversification.
• Ligand & Catalyst Development: Serves as a precursor for creating specialized nitrogen-containing ligands used in homogeneous catalysis and metal-organic frameworks (MOFs).
• Material Science Research: Employed in the synthesis of conjugated polymers and organic electronic materials due to its electron-deficient pyridine ring and polymerizable vinyl group.
• Cross-Coupling Reactions: An excellent substrate for Suzuki, Heck, and other palladium-catalyzed cross-coupling reactions to construct complex molecular architectures.
• Chemical Biology Probes: Utilized in the design and synthesis of molecular probes and tags for studying biological systems.
