Description

4,5-Dimethylfuran-2-Boronic Acid Pinacol Ester is a high-purity, protected boronic acid derivative essential for modern synthetic chemistry. Its primary value lies in serving as a key coupling partner in Suzuki-Miyaura cross-coupling reactions, enabling the efficient construction of complex biaryl and heterobiaryl structures. This compound is critically needed by research chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials industries for the synthesis of novel active ingredients and functional molecules.

Application

• Pharmaceutical Intermediate Synthesis: A crucial building block for constructing complex heterocyclic cores found in drug candidates, particularly in oncology and CNS therapeutic areas.
• Agrochemical Development: Used in the research and production of novel fungicides, herbicides, and insecticides that require specific furan-containing scaffolds.
• Material Science Research: Employed in the synthesis of organic electronic materials, such as polymers and small molecules for OLEDs and organic photovoltaics (OPVs).
• Catalyst & Ligand Preparation: Serves as a precursor for creating specialized ligands and catalysts used in asymmetric synthesis and other catalytic processes.
• Chemical Biology & Probe Development: Utilized in the design and synthesis of molecular probes and tags for studying biological systems and target engagement.
• Custom Synthesis & Contract Manufacturing: A key reagent for custom synthesis houses (CROs/CMOs) producing bespoke compounds for client projects.

Quality Control

Every batch of 4,5-Dimethylfuran-2-Boronic Acid Pinacol Ester is produced and tested under strict quality management protocols to ensure consistency and reliability for critical synthetic applications. Our standard grade typically meets a purity specification of ≥95% (by HPLC/NMR), with rigorous control of residual solvents and metallic impurities. Certificates of Analysis (COA) detailing identity, purity, and specific test results are provided with each shipment and 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 decomposition. Keep away from heat and incompatible materials.
