Description

Potassium(3-Ethoxyphenyl)Trifluoroboranuide is an organotrifluoroborate salt, a valuable and stable building block in modern synthetic chemistry. Its primary value lies in its utility as a coupling partner in Suzuki-Miyaura cross-coupling reactions, enabling the efficient construction of complex biaryl structures. This compound is particularly sought after by research chemists and process development scientists in the pharmaceutical and agrochemical industries for the synthesis of novel active ingredients and advanced intermediates.

Application

• Suzuki-Miyaura Cross-Coupling Reactions: Serves as a key, air- and moisture-stable boronic acid equivalent for forming carbon-carbon bonds between aryl groups.
• Pharmaceutical Intermediate Synthesis: Used in the research and development of active pharmaceutical ingredients (APIs), especially those containing substituted biphenyl or heterobiaryl motifs.
• Agrochemical Product Development: Employed in creating novel herbicides, fungicides, and insecticides that require specific aryl-aryl linkages.
• Material Science Research: Acts as a precursor for synthesizing organic electronic materials, such as those used in OLEDs or conductive polymers.
• Ligand and Catalyst Preparation: Useful for constructing complex organic ligands used in catalysis and coordination chemistry.
• Chemical Biology & Medicinal Chemistry: Facilitates the synthesis of molecular probes and tool compounds for biological target investigation.

Quality Control

Our Potassium(3-Ethoxyphenyl)Trifluoroboranuide is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity, critical for reproducible cross-coupling performance. All products undergo rigorous analytical testing, including NMR (1H, 11B, 19F) and HPLC analysis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (argon or nitrogen) and desiccated. Recommended long-term storage at 2-8°C.
