Description

Potassium (4-Methoxyphenyl)Trifluoroborate is an organoboron reagent widely used as a key synthetic intermediate in modern cross-coupling reactions. Its value lies in its enhanced stability and handling compared to corresponding boronic acids, offering superior performance in demanding pharmaceutical and fine chemical syntheses. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require reliable, high-purity building blocks for complex molecule construction.

Application

• Suzuki-Miyaura Cross-Coupling Reactions: A pivotal reagent for forming carbon-carbon bonds between aryl halides and this aryl boronate species, crucial for constructing biaryl structures found in many active pharmaceutical ingredients (APIs).
• Pharmaceutical Intermediate Synthesis: Serves as a versatile building block for the development of drug candidates, particularly in creating complex aromatic and heteroaromatic scaffolds.
• Agrochemical Research & Development: Used in the synthesis of novel herbicides, fungicides, and insecticides that require specific aryl-moiety incorporation.
• Ligand and Catalyst Preparation: Employed in the synthesis of specialized ligands for catalysis or as a precursor for materials science applications.
• Fine Chemical and Specialty Chemical Production: Integral for manufacturing dyes, electronic chemicals, and other high-value aromatic compounds.
• Academic and R&D Laboratories: A staple reagent for methodological development in organic synthesis and catalysis research.

Quality Control

Our Potassium (4-Methoxyphenyl)Trifluoroborate is manufactured under strict quality systems to ensure batch-to-batch consistency and high purity, typically meeting standards suitable for research and commercial synthesis. All products undergo rigorous analytical testing, including NMR (1H, 13C, 11B, 19F), HPLC, and elemental analysis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

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, the container should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use to prevent degradation. Recommended long-term storage at 2-8°C.
