Description

Potassium (2-Benzyloxyphenyl)Trifluoroborate is an organotrifluoroborate salt, a highly valuable and stable synthetic intermediate in modern cross-coupling chemistry. Its primary value lies in its exceptional stability to air and moisture compared to traditional boronic acids, while remaining highly reactive under Suzuki-Miyaura coupling conditions. This compound is essential for researchers and process chemists in the pharmaceutical, agrochemical, and advanced materials sectors who require reliable, shelf-stable building blocks for constructing complex biaryl and heterobiaryl architectures.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs) via palladium-catalyzed Suzuki-Miyaura cross-coupling reactions.
• Agrochemical Synthesis: Used in the research and development of novel herbicides, fungicides, and insecticides that require biaryl structural motifs.
• Ligand and Catalyst Development: Serves as a precursor for creating specialized ligands or functionalized materials in catalysis research.
• Material Science: Employed in the construction of organic electronic materials, such as those used in OLEDs and semiconductors, where precise aryl-aryl coupling is critical.
• Chemical Biology & Probe Synthesis: Useful for labeling and modifying biomolecules or creating fluorescent probes and sensors.
• Academic & Industrial R&D: A versatile reagent for methodological development and exploring new synthetic pathways in organic chemistry laboratories.

Quality Control

Our Potassium (2-Benzyloxyphenyl)Trifluoroborate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity, essential for reproducible results in sensitive coupling reactions. Each lot is analyzed using advanced techniques including NMR (¹H, ¹³C, ¹⁹F), HPLC, and KF Titration. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, the container should be kept tightly sealed under an inert atmosphere (argon or nitrogen) and desiccated for long-term storage to maintain optimal stability and reactivity. Recommended storage temperature: 2-8°C.
