Description

3,4-Dimethoxyphenylboronic Acid, Pinacol Ester is a protected boronic acid derivative, a crucial building block in modern synthetic organic chemistry. Its primary value lies in its enhanced stability compared to the free boronic acid, making it an ideal reagent for Suzuki-Miyaura cross-coupling reactions. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require reliable, high-purity intermediates for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds containing a 3,4-dimethoxyphenyl moiety.
• Agrochemical Synthesis: Used in the research and production of novel herbicides, fungicides, and insecticides through palladium-catalyzed cross-coupling.
• Material Science: Serves as a monomer or precursor in the development of organic electronic materials, such as polymers for OLEDs and organic photovoltaics.
• Ligand & Catalyst Development: Employed in the preparation of specialized ligands for asymmetric catalysis and metal-organic frameworks (MOFs).
• Chemical Research: A versatile reagent in academic and industrial R&D for constructing complex biaryl and heterobiaryl structures.
• Fine Chemical Production: Used in the manufacture of dyes, flavors, and fragrances that require specific aryl-aryl bond formations.

Quality Control

Our 3,4-Dimethoxyphenylboronic Acid, Pinacol Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure high chemical purity and identity. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are available for 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 should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
