Description

2,3-Difluoro-6-Ethoxyphenylboronic Acid is a specialized organoboron compound, a key building block in modern synthetic chemistry. Its value lies in its role as a versatile intermediate for constructing complex molecules via cross-coupling reactions, such as the Suzuki-Miyaura reaction. This high-purity boronic acid is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, where it is used to introduce the difluoroethoxybenzene moiety into target molecules, enabling the development of new active ingredients.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a difluorinated aromatic core.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and pesticides, where the fluorine atoms enhance biological activity and stability.
• Material Science Research: Serves as a monomer or building block for creating novel organic electronic materials, such as those used in OLEDs or semiconductors.
• Suzuki-Miyaura Cross-Coupling: The primary application is as a key reagent in palladium-catalyzed cross-coupling reactions to form biaryl and other carbon-carbon bonds.
• Ligand and Catalyst Development: Utilized in the preparation of specialized ligands for catalysis and metal-organic frameworks (MOFs).
• Life Sciences & Diagnostics: Can be incorporated into probes and markers for biochemical research and diagnostic assays.

Quality Control

Our 2,3-Difluoro-6-Ethoxyphenylboronic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and elemental analysis, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment 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 at 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) after opening to prevent moisture absorption and decomposition.
