Description

Borate(1-), [(3,4-Difluorophenyl)Methyl]Trifluoro-, Potassium (1:1), (T-4)- is a specialized organoboron potassium salt featuring a difluorobenzyl moiety, designed for advanced synthetic applications. This compound is valued for its role as a key synthetic intermediate or reagent in the development of complex molecules, particularly in pharmaceutical and agrochemical research. It is primarily sought by R&D chemists and process development scientists in the fine chemical, pharmaceutical, and advanced material sectors for constructing novel fluorinated and boron-containing architectures.

Application

• Pharmaceutical Intermediate: Serves as a critical building block in the synthesis of active pharmaceutical ingredients (APIs), especially those targeting CNS disorders or requiring fluorinated motifs for enhanced metabolic stability and bioavailability.
• Agrochemical Synthesis: Used in the research and development of novel pesticides and herbicides, where the boron and fluorine atoms contribute to unique modes of action and environmental persistence profiles.
• Material Science Precursor: Acts as a monomer or cross-linking agent in the development of specialty polymers, coatings, or electronic materials that benefit from boron's properties.
• Suzuki-Miyaura Cross-Coupling: Functions as an organoboron reagent (potassium trifluoroborate salt) in palladium-catalyzed cross-coupling reactions to form carbon-carbon bonds, a cornerstone of modern synthetic chemistry.
• Chemical Biology & Proteomics: Employed as a tool compound or probe in biochemical research, leveraging boron's ability to interact with biological targets or as a handle for further bioconjugation.
• Ligand Synthesis for Catalysis: Used to prepare novel bidentate or tridentate ligands for transition metal catalysts used in asymmetric synthesis and other catalytic processes.

Quality Control

Our production of this advanced intermediate adheres to strict quality control protocols to ensure batch-to-batch consistency and high purity, essential for sensitive synthetic applications. Each lot is characterized using advanced analytical techniques including NMR, HPLC, and elemental analysis. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment. We support development under cGMP guidelines for pharmaceutical applications upon request.

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 in a dry environment to prevent moisture absorption, which can compromise stability and reactivity. Keep away from incompatible materials such as strong acids and strong oxidizing agents.
