Description

Potassium 4-Bromophenyltrifluoroborate is a versatile and highly valuable organoboron reagent, specifically a potassium aryltrifluoroborate salt. This compound is prized for its enhanced stability and handling characteristics compared to traditional boronic acids, making it a superior choice for demanding synthetic protocols. It is a critical building block for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors, enabling key carbon-carbon bond-forming reactions.

Application

• Suzuki-Miyaura Cross-Coupling Reactions: A key reagent for the palladium-catalyzed coupling with aryl or vinyl halides to create biaryl structures, a core motif in many active pharmaceutical ingredients (APIs) and organic electronic materials.
• Pharmaceutical Intermediate Synthesis: Used in the research and production of complex drug molecules, particularly those containing substituted biphenyl or heterobiaryl scaffolds.
• Agrochemical Development: Serves as a building block for creating novel herbicides, fungicides, and insecticides with specific activity profiles.
• Ligand and Catalyst Preparation: Employed in the synthesis of specialized phosphine or N-heterocyclic carbene (NHC) ligands containing bromophenyl groups.
• Material Science Research: Useful in constructing organic frameworks, polymers, and liquid crystals where precise aromatic spacing and bromine functionality are required.
• Chemical Biology & Probe Development: Facilitates the site-specific labeling or functionalization of biomolecules and the creation of molecular probes for imaging or diagnostic applications.

Quality Control

Our Potassium 4-Bromophenyltrifluoroborate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR (1H, 13C, 11B, 19F), HPLC, and elemental analysis (EA), to ensure identity, purity, and consistency. Certificates of Analysis (COA) with detailed specifications are provided for every shipment, supporting your quality assurance and regulatory compliance needs.

Storage

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