Description

4-Benzylbenzeneboronic Acid Pinacol Ester, 97% is a high-purity organoboron compound, specifically a protected boronic acid derivative. This product is a critical synthetic intermediate valued for its enhanced stability and handling properties compared to the free boronic acid. It is primarily utilized by research and development chemists and process engineers in the pharmaceutical and advanced materials sectors for constructing complex molecular architectures via Suzuki-Miyaura cross-coupling reactions.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs) and drug candidates, particularly those containing biphenyl or substituted aromatic systems.
• Suzuki-Miyaura Cross-Coupling: Serves as a stable, air-tolerant arylboron reagent for palladium-catalyzed carbon-carbon bond formation, enabling the creation of complex biaryl structures.
• Material Science Research: Used in the development of organic electronic materials, such as polymers and small molecules for OLEDs or organic photovoltaics.
• Agrochemical Synthesis: Employed as an intermediate in the research and production of advanced crop protection agents and herbicides.
• Ligand and Catalyst Development: Acts as a precursor for creating novel ligands or functionalized materials in catalysis research.
• Chemical Biology Probes: Utilized in the synthesis of molecular probes and tools for studying biological processes.

Quality Control

Our 4-Benzylbenzeneboronic Acid Pinacol Ester, 97% is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and GC analysis, to ensure identity, purity, and consistency meet the specified standard. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment and is available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize moisture uptake. Recommended storage temperature: 2-8°C.
