Description

Potassium 4-Formylphenyltrifluoroborate is a versatile and valuable organoboron reagent, specifically a potassium aryltrifluoroborate salt bearing a formyl functional group. This compound is essential for high-precision Suzuki-Miyaura cross-coupling reactions, enabling the efficient construction of biaryl and conjugated systems critical in advanced material and pharmaceutical synthesis. It is primarily sought after by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and material science industries for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate Synthesis: A key building block for creating novel active pharmaceutical ingredients (APIs) and drug candidates via palladium-catalyzed cross-coupling.
• Agrochemical Research: Used in the development of new herbicides, fungicides, and insecticides that require specific biaryl structures.
• Material Science & OLED Development: Facilitates the synthesis of conjugated organic molecules for use in organic light-emitting diodes (OLEDs), semiconductors, and liquid crystals.
• Ligand and Catalyst Preparation: Serves as a precursor for synthesizing specialized ligands and catalysts used in asymmetric synthesis and other catalytic processes.
• Chemical Biology & Probe Development: Employed in the creation of molecular probes and bioconjugates for diagnostic and research applications.
• Academic & Industrial R&D: A fundamental reagent for methodological development in organic synthesis and scale-up process optimization.

Quality Control

Our Potassium 4-Formylphenyltrifluoroborate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR (1H, 13C, 11B, 19F), HPLC for purity, and KF titration for moisture content, to ensure consistency and compliance with research and development standards. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

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. This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (argon/nitrogen) when possible to maintain stability and purity. Keep the container tightly sealed in a desiccator after opening.
