Description

Potassium (3-Fluoro-4-Formylphenyl)Trifluoroborate is a high-value organotrifluoroborate salt, a crucial building block in modern synthetic chemistry. Its primary value lies in its exceptional stability and reactivity, serving as a superior alternative to traditional boronic acids in cross-coupling reactions. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, where it is used to introduce the versatile 3-fluoro-4-formylphenyl moiety into complex molecular architectures.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for molecules containing fluorinated aromatic aldehydes.
• Suzuki-Miyaura Cross-Coupling Reactions: Acts as a stable, air- and moisture-tolerant coupling partner for the construction of biaryl and heterobiaryl systems under mild conditions.
• Agrochemical Synthesis: Used in the research and development of novel herbicides, fungicides, and insecticides that benefit from the physicochemical properties of fluorine.
• Material Science Research: Employed in the creation of advanced organic materials, such as liquid crystals, polymers, and organic light-emitting diodes (OLEDs).
• Chemical Biology & Probe Development: Facilitates the synthesis of fluorinated molecular probes and tags for imaging and diagnostic applications.
• Scale-up Process Chemistry: Its improved handling characteristics make it suitable for kilogram-scale manufacturing processes in fine chemical production.

Quality Control

Our Potassium (3-Fluoro-4-Formylphenyl)Trifluoroborate is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including NMR (1H, 13C, 19F, 11B) and HPLC analysis, to ensure high chemical purity and consistent lot-to-lot performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can affect stability and reactivity. Keep away from incompatible materials such as strong acids and strong oxidizing agents.
