Description

2-Ethyl-6-Methylphenylboronic Acid is a specialized organoboron compound widely used as a key building block in modern synthetic chemistry. Its primary value lies in its role as a versatile coupling partner in Suzuki-Miyaura cross-coupling reactions, enabling the efficient construction of complex biaryl and heterobiaryl structures. This high-purity intermediate is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require reliable, high-quality reagents for developing active ingredients and functional molecules.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds containing substituted biphenyl or heterocyclic motifs.
• Agrochemical Synthesis: Used in the research and production of novel herbicides, fungicides, and insecticides that require specific aryl-aryl linkages.
• Material Science Research: Serves as a monomer or building block for creating organic electronic materials, such as those used in OLEDs and organic photovoltaics.
• Ligand and Catalyst Development: Employed in the preparation of novel palladium ligands and other metal-organic frameworks (MOFs) for catalytic applications.
• Chemical Biology Probes: Utilized in the design and synthesis of molecular probes and tags for studying biological processes.
• Custom Synthesis & Contract Manufacturing: A valuable reagent for custom synthesis houses and CDMOs (Contract Development and Manufacturing Organizations) serving the life sciences industry.

Quality Control

Every batch of our 2-Ethyl-6-Methylphenylboronic Acid is manufactured under strict quality management systems and undergoes rigorous analytical testing to ensure it meets the high-purity standards required for sensitive coupling reactions. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as purity (by HPLC/NMR), boronic acid content, and impurity profiles. Our quality commitment supports compliance with cGMP guidelines for pharmaceutical intermediates and other demanding applications.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and easily oxidized nature, this material should be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended long-term storage temperature is 2-8°C. Allow the sealed container to reach room temperature before opening to prevent moisture condensation.
