Description

2-(3-Ethenylphenyl)-4,4,5,5-Tetramethyl-1,3,2-Dioxaborolane is a high-purity boronic ester derivative, a critical intermediate in modern synthetic chemistry. Its primary value lies in enabling efficient Suzuki-Miyaura cross-coupling reactions, a cornerstone methodology for constructing complex biaryl and conjugated systems. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require reliable, high-quality building blocks for drug discovery, crop protection agents, and organic electronic materials.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs) and drug candidates, particularly those containing biphenyl or styrenyl motifs.
• Agrochemical Synthesis: Used in the research and production of novel herbicides, fungicides, and insecticides that require specific aryl-aryl linkages.
• Organic Light-Emitting Diodes (OLEDs): Serves as a precursor for constructing electron-transport or emissive layer materials in display and lighting technologies.
• Polymer & Material Science: Enables the incorporation of phenylvinyl groups into polymers and specialty materials to modify properties like rigidity, thermal stability, or optical characteristics.
• Ligand & Catalyst Development: Utilized in the preparation of novel ligands and organometallic catalysts for asymmetric synthesis and other catalytic processes.
• Chemical Research & Development: A versatile reagent for academic and industrial R&D labs exploring new C-C bond-forming methodologies and complex molecule synthesis.
