Description

Potassium Benzofurazan-5-Trifluoroborate is a versatile organotrifluoroborate salt, a crucial class of reagents in modern synthetic chemistry. Its primary value lies in its exceptional stability and reactivity, making it an ideal coupling partner in Suzuki-Miyaura cross-coupling reactions for constructing complex aromatic and heteroaromatic systems. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require reliable, high-purity building blocks for drug discovery, ligand synthesis, and material science applications.

Application

• Pharmaceutical Intermediates: A key building block in the synthesis of active pharmaceutical ingredients (APIs) and novel drug candidates via palladium-catalyzed cross-coupling.
• Agrochemical Synthesis: Used in the development of advanced herbicides, fungicides, and insecticides requiring specific benzofurazan-based scaffolds.
• Material Science & OLED Development: Serves as a precursor for creating organic light-emitting diode (OLED) materials and other functional organic electronic compounds.
• Ligand & Catalyst Preparation: Employed in the synthesis of specialized ligands for catalysis and metal-organic frameworks (MOFs).
• Chemical Biology & Bioconjugation: Useful for tagging and modifying biomolecules due to the reactivity of the trifluoroborate group under mild conditions.
• Academic & Industrial R&D: A fundamental reagent for method development and exploring new synthetic pathways in organic chemistry laboratories.

Quality Control

Our Potassium Benzofurazan-5-Trifluoroborate is manufactured under strict quality management protocols. Every batch undergoes rigorous analytical testing, including NMR (¹H, ¹³C, ¹⁹F), HPLC for purity assessment, and KF titration for moisture content, to ensure it meets the high standards required for sensitive cross-coupling reactions. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing all specifications and test results.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 15-25°C. This product is hygroscopic (moisture-sensitive) and must be handled under an inert atmosphere (argon/nitrogen) for long-term stability. Keep the container tightly sealed in a desiccator when not in use.
