Description

Dicyclohexyl(9-benzylfluoren-9-yl)phosphonium tetrafluoroborate (Catacxium FBN) is a high-purity, specialized phosphonium salt catalyst essential for advanced organic synthesis. This compound matters because it serves as a highly effective and selective catalyst for challenging cross-coupling and olefin metathesis reactions, enabling the production of complex molecules with high efficiency. It is primarily needed by research and development laboratories, pharmaceutical intermediates manufacturers, and fine chemical producers working on innovative drug candidates and high-value specialty chemicals.

Application

• Pharmaceutical Intermediate Synthesis: A key catalyst for Buchwald-Hartwig amination, Suzuki-Miyaura, and other palladium-catalyzed cross-coupling reactions critical for constructing C-N and C-C bonds in active pharmaceutical ingredients (APIs).
• Advanced Material Research: Used in the development of organic light-emitting diodes (OLEDs), conductive polymers, and other functional materials requiring precise molecular architecture.
• Agrochemical Development: Facilitates the synthesis of novel, complex herbicide and pesticide molecules with improved efficacy and environmental profiles.
• Academic & Industrial R&D: An indispensable tool for methodological development in organic chemistry and for scaling up novel synthetic routes from lab to pilot plant.
• Olefin Metathesis Catalyst Precursor: Serves as a precursor for generating highly active ruthenium-based metathesis catalysts used in polymer and macrocycle synthesis.

Quality Control

Our Catacxium FBN is manufactured under strict quality control protocols to ensure batch-to-batch consistency and a minimum purity of 97%. Each lot is fully characterized using advanced analytical techniques including NMR (1H, 13C, 31P, 19F), HPLC, and mass spectrometry to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment, supporting compliance in cGMP and ISO 9001 environments for critical R&D and production applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (argon or nitrogen) when possible to maintain optimal stability and catalytic activity. Keep the container tightly sealed in a desiccator for long-term storage.
