Description

Potassium 4-Butylphenyltrifluoroborate is an organotrifluoroborate salt, a versatile and stable synthetic intermediate prized for its utility in cross-coupling reactions. Its primary value lies in enabling the efficient and selective construction of complex organic molecules, particularly in pharmaceutical and advanced material synthesis. This compound is essential for R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries who require reliable, high-purity building blocks.

Application

• Suzuki-Miyaura Cross-Coupling Reactions: A key boron reagent for forming carbon-carbon bonds between aryl or vinyl groups, crucial for synthesizing complex biaryl structures found in active pharmaceutical ingredients (APIs).
• Pharmaceutical Intermediate: Used in the research and production of drug candidates, especially those requiring the 4-butylphenyl moiety for biological activity or pharmacokinetic optimization.
• Agrochemical Synthesis: Serves as a building block for creating novel herbicides, fungicides, and insecticides with specific activity profiles.
• Material Science Research: Employed in the development of organic electronic materials, such as semiconductors for OLEDs or OFETs, where precise molecular architecture is critical.
• Ligand and Catalyst Development: Useful for synthesizing novel ligands or metal-organic frameworks (MOFs) with tailored properties.
• Chemical Biology Probes: Acts as a precursor for creating labeled compounds or probes used in biochemical and medicinal chemistry research.

Quality Control

Our Potassium 4-Butylphenyltrifluoroborate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR (1H, 11B, 19F) and HPLC analysis, to ensure high chemical purity and consistent performance in sensitive coupling reactions. Certificates of Analysis (COA) with full characterization data are available upon request.

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 should be handled under an inert atmosphere (e.g., nitrogen or argon) for prolonged use to maintain stability and purity.
