Description

3,4-Dichloro-2-Methoxyphenylboronic Acid is a specialized organoboron compound serving as a crucial building block in modern synthetic chemistry. Its value lies in its role as a key intermediate for constructing complex molecular architectures via cross-coupling reactions, most notably the Suzuki-Miyaura reaction. This high-purity boronic acid is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require reliable, high-quality intermediates for drug discovery, active ingredient synthesis, and material science applications.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds containing a substituted phenyl moiety.
• Agrochemical Synthesis: Used in the research and development of novel herbicides, fungicides, and insecticides, leveraging its halogenated structure.
• Material Science Research: Serves as a monomer or building block for creating organic electronic materials, such as those used in OLEDs or organic semiconductors.
• Cross-Coupling Reactions: Primarily employed in Suzuki-Miyaura cross-coupling to form biaryl and other carbon-carbon bonds under mild conditions.
• Ligand and Catalyst Development: Utilized in the preparation of novel ligands for catalysis or as a scaffold in metal-organic frameworks (MOFs).
• Chemical Biology & Proteomics: Acts as a handle for bioconjugation or in the development of molecular probes and sensors.

Quality Control

Our 3,4-Dichloro-2-Methoxyphenylboronic 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. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is 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 (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
