Description

Potassium (4-Cyanophenyl)Trifluoroborate is an organotrifluoroborate salt, a highly valuable building block in modern synthetic chemistry. Its primary value lies in its exceptional stability and utility 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-purity 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: Serves as a building block for creating organic electronic materials, such as those used in OLEDs and organic semiconductors.
• Ligand and Catalyst Development: Employed in the preparation of specialized ligands and organometallic catalysts for asymmetric synthesis.
• Chemical Research: A versatile reagent in academic and industrial R&D for exploring new carbon-carbon bond-forming methodologies.
• Fine Chemical Production: Integral to the manufacture of complex dyes, pigments, and specialty performance chemicals.

Quality Control

Our Potassium (4-Cyanophenyl)Trifluoroborate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity, typically exceeding 97%. Each lot is characterized by NMR (¹H, ¹¹B, ¹³C), HPLC, and KF titration to confirm identity, purity, and moisture content. Certificates of Analysis (COA) detailing all specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 2-8°C. This product is hygroscopic (moisture-sensitive) and must be handled under an inert atmosphere (argon or nitrogen) to prevent decomposition. Keep away from strong acids and strong oxidizing agents.
