Description

Potassium 2-Bromophenyltrifluoroborate is a versatile and highly valuable organoboron reagent, specifically an aryltrifluoroborate salt. This compound is a critical building block in modern synthetic chemistry, enabling efficient and selective carbon-carbon bond formation. It is primarily sought after by researchers and process chemists in the pharmaceutical, agrochemical, and advanced materials industries for constructing complex molecular architectures. Its stability and reactivity profile make it a preferred choice for Suzuki-Miyaura cross-coupling reactions.

Application

• Pharmaceutical Intermediate Synthesis: A key precursor for constructing biaryl and heterobiaryl scaffolds found in active pharmaceutical ingredients (APIs).
• Agrochemical Development: Used in the synthesis of novel herbicides, fungicides, and insecticides requiring specific brominated aryl motifs.
• Material Science Research: Serves as a monomer or building block for creating organic electronic materials, such as polymers for OLEDs and semiconductors.
• Suzuki-Miyaura Cross-Coupling Reactions: The primary application, where it acts as a stable, air- and moisture-tolerant coupling partner with various organic halides.
• Ligand and Catalyst Preparation: Utilized in the synthesis of specialized ligands and organometallic catalysts.
• Chemical Biology & Probe Development: Enables the site-specific introduction of bromophenyl groups into biomolecules or fluorescent probes.

Quality Control

Our Potassium 2-Bromophenyltrifluoroborate is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity for demanding synthetic applications. Each lot undergoes comprehensive analytical testing, including NMR (¹H, ¹³C, ¹⁹F), HPLC for purity assessment, and KF titration for moisture content. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with our stringent specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C. This product is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (argon or nitrogen) for long-term storage and to maintain optimal reactivity. Keep the container tightly sealed in a desiccator when not in use.
