Description

3,5-Dimethyl-4-Ethoxyphenylboronic Acid is a high-purity organoboron compound, specifically a substituted phenylboronic acid, serving as a critical 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 structures. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors, where it is used to develop active pharmaceutical ingredients (APIs), novel crop protection agents, and functional organic molecules.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of complex drug molecules and active pharmaceutical ingredients (APIs) via palladium-catalyzed cross-coupling reactions.
• Agrochemical Synthesis: Used in the research and production of novel herbicides, fungicides, and insecticides that require specific biaryl motifs.
• Material Science Research: Serves as a monomer or building block for creating organic electronic materials, such as those used in OLEDs and organic photovoltaics.
• Chemical Biology & Proteomics: Utilized in the development of molecular probes and sensors that leverage boronic acid-diol interactions for carbohydrate recognition.
• Ligand & Catalyst Development: Acts as a starting material for synthesizing specialized ligands used in homogeneous catalysis.
• Custom Synthesis & Contract Manufacturing: Employed by fine chemical companies for bespoke synthesis projects requiring specific, substituted phenylboronic acid derivatives.

Quality Control

Our 3,5-Dimethyl-4-Ethoxyphenylboronic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR for structural confirmation, and Karl Fischer titration for moisture content, to ensure it meets the high standards required for sensitive cross-coupling applications. Certificates of Analysis (COA) documenting all critical quality attributes are 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 nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation.
