Description

Potassium (4-tert-Butylphenyl)Trifluoroborate is an organotrifluoroborate salt, a highly valuable and stable synthetic intermediate in modern cross-coupling chemistry. This compound matters because it offers superior handling stability and reactivity compared to traditional boronic acids, enabling more efficient and reliable synthesis of complex organic molecules. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials industries for constructing biaryl and other carbon-carbon bonds.

Application

• Suzuki-Miyaura Cross-Coupling Reactions: A key reagent for the palladium-catalyzed formation of carbon-carbon bonds between aryl halides and this boronate ester equivalent.
• Pharmaceutical Intermediate Synthesis: Used in the research and production of active pharmaceutical ingredients (APIs) containing substituted biphenyl or terphenyl motifs.
• Agrochemical Development: Employed in creating novel herbicides, fungicides, and insecticides that require specific aryl-aryl linkages.
• Ligand and Catalyst Preparation: Serves as a building block for synthesizing specialized phosphine or N-heterocyclic carbene ligands.
• Material Science Research: Useful in the development of organic electronic materials, such as those for OLEDs or semiconductors, where precise molecular architecture is critical.
• Chemical Biology Probes: Facilitates the synthesis of labeled compounds or molecular probes for biochemical and diagnostic applications.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards for research and process chemistry. Each batch is characterized by NMR (¹H, ¹³C, ¹⁹F) and HPLC analysis to confirm identity and high purity. Certificates of Analysis (COA) with detailed chromatographic data are available upon request. We adhere to strict in-house quality protocols to guarantee batch-to-batch consistency and reliability for your synthetic workflows.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, it is recommended to handle the material under an inert atmosphere (e.g., nitrogen or argon) for long-term storage and to minimize exposure to ambient moisture. Ideal storage temperature is 2-8°C.
