Description

Borate(1-), Tetrakis(3,5-Difluorophenyl)-, Sodium(1:1) is a specialized organoboron compound that serves as a critical reagent and intermediate in advanced synthetic chemistry. Its unique structure, featuring four electron-deficient difluorophenyl groups coordinated to a borate anion, makes it an excellent precursor for generating highly active, sterically hindered catalysts and ligands. This compound is essential for researchers and manufacturers in the pharmaceutical and advanced materials sectors who require precise control over polymerization and cross-coupling reactions to develop novel active pharmaceutical ingredients (APIs) and high-performance polymers.

Application

• Catalyst Precursor for Olefin Polymerization: Used to generate highly active metallocene and non-metallocene catalysts for the production of polyolefins with specific tacticity and molecular weight distributions.
• Anionic Initiator for Living Polymerization: Employed in the controlled anionic polymerization of styrenics, dienes, and (meth)acrylates to create block copolymers and polymers with narrow polydispersity.
• Ligand Synthesis for Cross-Coupling Catalysts: Acts as a key building block for synthesizing sophisticated phosphine and N-heterocyclic carbene (NHC) ligands used in Suzuki, Heck, and Buchwald-Hartwig amination reactions.
• Electrolyte Additive for Batteries: Investigated as a potential additive in electrolyte formulations for lithium-ion and lithium-metal batteries to improve SEI (Solid Electrolyte Interphase) stability and cycle life.
• Organic Synthesis Intermediate: Serves as a versatile reagent for introducing the tetrakis(3,5-difluorophenyl)borate anion into other molecules to modify solubility, acidity, or catalytic activity.
• Component in OLED Materials: Utilized in the research and development of electron-transport materials and host materials for organic light-emitting diodes (OLEDs).

Quality Control

Our production of Sodium Tetrakis(3,5-difluorophenyl)borate adheres to stringent quality protocols to ensure batch-to-batch consistency and reliability for sensitive synthetic applications. Each lot is characterized using advanced analytical techniques including NMR (1H, 11B, 19F), HPLC, and elemental analysis. Certificates of Analysis (COA) detailing purity, identity, and key impurity profiles are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (argon or nitrogen) after opening to prevent moisture absorption and decomposition. Keep away from incompatible materials such as strong acids and oxidizing agents.
