Description

3,3'-Bis(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)-1,1'-Biphenyl is a high-purity, bifunctional boronic ester derivative that serves as a critical building block in advanced organic synthesis. Its value lies in providing two protected boronic acid functionalities on a rigid biphenyl core, enabling efficient cross-coupling reactions to construct complex molecular architectures. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and materials science industries, particularly for developing active pharmaceutical ingredients (APIs), organic electronic materials, and liquid crystals.

Application

• Pharmaceutical Intermediate: A key precursor in Suzuki-Miyaura cross-coupling reactions for synthesizing novel drug candidates, especially biphenyl-based molecules.
• Agrochemical Synthesis: Used to create advanced active ingredients for crop protection products through efficient carbon-carbon bond formation.
• Organic Electronic Materials: Serves as a monomer for constructing conjugated polymers and small molecules used in OLEDs, OFETs, and organic photovoltaics.
• Liquid Crystal Production: Employed in the synthesis of biphenyl-based mesogens for display technologies.
• Metal-Organic Framework (MOF) Linker: Utilized as an organic linker precursor to create functional porous materials for gas storage and catalysis.
• Chemical Research & Development: A versatile reagent in academic and industrial R&D for exploring new synthetic pathways and creating complex organic structures.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is analyzed to confirm identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with detailed results from advanced analytical techniques. Our quality management system supports the needs of cGMP manufacturing for pharmaceutical applications, and we can accommodate custom purity requirements upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation. Keep away from incompatible materials.
