Description

Potassium 3,5-Dichlorophenyltrifluoroborate is a versatile organoboron reagent, specifically an aryltrifluoroborate salt, prized for its enhanced stability and handling properties compared to traditional boronic acids. This compound serves as a critical building block in modern synthetic chemistry, particularly in transition-metal-catalyzed cross-coupling reactions like the Suzuki-Miyaura reaction, enabling the efficient construction of complex biaryl structures. It is essential for researchers and process chemists 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, especially those containing dichlorophenyl motifs.
• Agrochemical Synthesis: Used in creating herbicides, fungicides, and insecticides where the 3,5-dichlorophenyl group imparts specific biological activity.
• Material Science: Employed in the development of organic electronic materials, ligands for catalysts, and liquid crystals.
• Suzuki-Miyaura Cross-Coupling: Acts as a stable, air- and moisture-tolerant coupling partner with various organic halides to form carbon-carbon bonds.
• Chemical Research & Development: A valuable tool for medicinal chemistry and process optimization in R&D laboratories.
• Ligand and Complex Preparation: Serves as a starting material for synthesizing specialized ligands used in homogeneous catalysis.

Quality Control

Our Potassium 3,5-Dichlorophenyltrifluoroborate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and elemental analysis, to ensure high purity and consistency. Certificates of Analysis (COA) detailing lot-specific results are provided with every shipment. We support compliance with relevant regulatory frameworks for research and industrial use.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to maintain stability and purity. Keep away from incompatible materials.
