Description

1,3,2-Dioxaborolane, 2-(2,2-Diphenylethenyl)-4,4,5,5-Tetramethyl- is a specialized organoboron compound featuring a dioxaborolane (pinacol boronate ester) core functionalized with a diphenylethenyl group. This structure makes it a valuable versatile building block and reagent in advanced synthetic chemistry, particularly for cross-coupling reactions. It is primarily utilized by pharmaceutical researchers and material scientists developing novel organic electronic materials and active pharmaceutical ingredients (APIs).

Application

• Suzuki-Miyaura Cross-Coupling Reactions: A key reagent for forming carbon-carbon bonds between the boronate ester and aryl/vinyl halides, essential for constructing complex molecular architectures.
• Pharmaceutical Intermediate Synthesis: Used in the research and development of new drug candidates, especially those requiring conjugated aromatic or styrenyl systems.
• Organic Light-Emitting Diode (OLED) Materials: Serves as a precursor for synthesizing emissive or charge-transporting layers in display and lighting technologies.
• Organic Semiconductor Development: Employed in creating π-conjugated polymers and small molecules for use in organic field-effect transistors (OFETs) and photovoltaics.
• Ligand and Catalyst Preparation: Can be used to introduce functional groups that modify the properties of catalysts or create novel ligands for metal complexes.
• Polymer Chemistry: Acts as a monomer or functionalization agent in the synthesis of advanced polymers with specific electronic or optical properties.

Quality Control

Our high-purity organoboron reagents are manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR (1H, 13C, 11B), and GC analysis, to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your R&D and quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); containers must be kept tightly sealed under an inert atmosphere (argon or nitrogen) to prevent hydrolysis and maintain product integrity. Keep away from heat and incompatible materials.
