Description

Potassium 3-Formylphenyltrifluoroborate is a versatile and highly valuable organoboron reagent, specifically a potassium aryltrifluoroborate salt bearing a formyl functional group. This compound is essential for modern synthetic chemistry, enabling efficient and selective carbon-carbon bond formation through Suzuki-Miyaura cross-coupling reactions. It is primarily utilized by research chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials industries to construct complex molecular architectures. The presence of the reactive formyl group allows for further synthetic elaboration, making it a critical building block for drug discovery and fine chemical synthesis.

Application

• Pharmaceutical Intermediate Synthesis: A key building block for constructing biaryl and heterobiaryl scaffolds prevalent in active pharmaceutical ingredients (APIs) via palladium-catalyzed cross-coupling.
• Agrochemical Research: Used in the development of novel herbicides, fungicides, and insecticides that require specific aryl-aldehyde motifs.
• Material Science & OLED Development: Serves as a precursor for creating conjugated organic molecules used in organic light-emitting diodes (OLEDs) and other electronic materials.
• Ligand & Catalyst Design: The formyl group facilitates the synthesis of novel chelating ligands for catalysis and metal-organic frameworks (MOFs).
• Academic & R&D Laboratories: A fundamental reagent for methodological development in organic synthesis and exploring new coupling methodologies.
• Fine Chemical Production: Employed in the multi-step synthesis of specialty chemicals, flavors, and fragrances requiring precise aryl group incorporation.

Quality Control

Our Potassium 3-Formylphenyltrifluoroborate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including NMR (1H, 13C, 19F, 11B) for structural confirmation and HPLC purity analysis. We provide full traceability and ensure compliance with relevant industry standards for research and development. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are available for every shipment upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C (refrigerated) or as specified on the label. Due to its hygroscopic nature, the container must be kept tightly sealed in a desiccated environment to prevent moisture absorption and decomposition. Handle and store under an inert atmosphere (argon or nitrogen) for long-term stability.
