Description

Potassium Trifluoro(Naphthalen-2-Ylmethyl)Borate is a specialized organoboron salt, also known as a potassium trifluoroborate salt, characterized by its naphthylmethyl functional group. This compound serves as a valuable, air- and moisture-stable precursor for Suzuki-Miyaura cross-coupling reactions, a cornerstone methodology in modern synthetic organic chemistry. It is primarily utilized by researchers and process chemists in the pharmaceutical, agrochemical, and advanced materials sectors for the efficient construction of complex biaryl and heterobiaryl structures. The product's stability offers significant handling advantages over traditional boronic acids, facilitating streamlined synthesis and purification workflows.

Application

• Pharmaceutical Intermediate Synthesis: A key building block for creating active pharmaceutical ingredients (APIs) and drug candidates, particularly those containing naphthalene or extended aromatic systems.
• Agrochemical Development: Used in the research and production of novel herbicides, fungicides, and insecticides where specific aryl-aryl linkages are required for bioactivity.
• Material Science & Organic Electronics: Employed in the synthesis of organic semiconductors, light-emitting diodes (OLEDs), and conductive polymers that benefit from rigid, planar naphthalene-based architectures.
• Ligand and Catalyst Preparation: Serves as a precursor for synthesizing specialized ligands and metal-organic complexes used in catalysis.
• Chemical Research & Development: A versatile reagent in academic and industrial R&D labs for method development and exploring new chemical spaces via cross-coupling.
• Fine Chemical Production: Enables the scalable manufacture of complex, high-value aromatic compounds for various specialty chemical applications.

Quality Control

Our Potassium Trifluoro(Naphthalen-2-Ylmethyl)Borate is produced under stringent quality management protocols. Each batch undergoes rigorous analytical testing, including NMR (1H, 13C, 19F, 11B), HPLC, and elemental analysis, to ensure high purity and consistent performance as a coupling partner. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, the container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture uptake and decomposition. Recommended long-term storage temperature is 2-8°C.
