Description

Potassium (2-Cyanophenyl)Trifluoroborate is a high-purity organotrifluoroborate salt, a versatile and stable building block in modern synthetic chemistry. Its primary value lies in its exceptional utility as a 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 industries 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 biphenyl or substituted phenyl motifs.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and insecticides that require specific aryl-aryl linkages.
• Material Science Research: Serves as a building block for creating organic electronic materials, liquid crystals, and polymers with tailored properties.
• Suzuki-Miyaura Cross-Coupling: The primary application is as a stable, air- and moisture-tolerant boronic acid surrogate in palladium-catalyzed cross-coupling reactions with aryl halides.
• Chemical Library Development: Enables the rapid, parallel synthesis of diverse compound libraries for high-throughput screening in drug discovery programs.
• Ligand and Catalyst Synthesis: Employed in the preparation of specialized ligands and organometallic catalysts.

Quality Control

Our Potassium (2-Cyanophenyl)Trifluoroborate is manufactured under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including NMR (1H, 13C, 19F, 11B), HPLC, and elemental analysis. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (argon or nitrogen) and desiccated to maintain product integrity. Recommended long-term storage at 2-8°C.
