Description

4-Ethoxy-2-Methoxyphenylboronic Acid is a high-purity boronic acid derivative, a critical building block in modern synthetic organic chemistry. Its value lies in its role as a key coupling partner in Suzuki-Miyaura cross-coupling reactions, enabling the efficient construction of complex biaryl structures. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require reliable, high-quality intermediates for drug discovery and specialty chemical synthesis.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs) and drug candidates, particularly those containing complex diaryl or heterobiaryl motifs.
• Agrochemical Synthesis: Used in the research and development of novel herbicides, fungicides, and insecticides that require specific aryl-aryl linkages.
• Material Science: Serves as a monomer or building block for creating organic electronic materials, such as those used in OLEDs and organic photovoltaics.
• Chemical Research: A versatile reagent in academic and industrial R&D labs for methodology development and the construction of compound libraries via cross-coupling chemistry.
• Ligand Synthesis: Used to prepare sophisticated boronic acid-based ligands for catalysis and sensor applications.

Quality Control

Every batch of 4-Ethoxy-2-Methoxyphenylboronic Acid is manufactured under strict quality management protocols. Our products undergo rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure compliance with exacting purity standards. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled 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.
