Description

Potassium (3-Methylphenyl)Trifluoroborate is a versatile organoboron reagent, specifically a potassium aryltrifluoroborate salt, widely used in modern synthetic chemistry. Its primary value lies in its enhanced stability and handling properties compared to traditional boronic acids, making it a crucial building block for efficient cross-coupling reactions. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require reliable and high-purity intermediates for constructing complex molecular architectures.

Application

• Suzuki-Miyaura Cross-Coupling Reactions: A key reagent for forming carbon-carbon bonds between aryl halides and this trifluoroborate salt, enabling the synthesis of biaryl structures common in active pharmaceutical ingredients (APIs).
• Pharmaceutical Intermediate Synthesis: Used in the research and production of drug candidates, particularly those containing substituted biphenyl or heterobiaryl motifs.
• Agrochemical Manufacturing: Serves as a precursor in creating novel herbicides, fungicides, and insecticides with specific activity profiles.
• Ligand and Catalyst Development: Employed in the synthesis of specialized ligands for catalysis and in the development of new organometallic complexes.
• Material Science Research: A building block for creating organic electronic materials, such as those used in OLEDs and conductive polymers.
• Chemical Biology & Probe Synthesis: Useful for incorporating stable boron-containing tags or labels into molecules for imaging and diagnostic applications.

Quality Control

Our Potassium (3-Methylphenyl)Trifluoroborate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is subjected to rigorous analytical testing, including NMR (1H, 11B, 19F), HPLC, and elemental analysis, to confirm identity, potency, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all specifications and test results is provided with every shipment to support your quality assurance and regulatory needs.

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, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) in a desiccator for long-term stability. Recommended storage temperature is 2-8°C.
