Description

Potassium Phenyltrifluoroborate is an organoboron reagent widely used as a stable, air- and moisture-tolerant alternative to boronic acids in cross-coupling reactions. This compound is a critical building block in modern synthetic organic chemistry, enabling the efficient formation of carbon-carbon bonds under mild conditions. It is essential for researchers and process chemists in the pharmaceutical, agrochemical, and advanced materials industries who require reliable and scalable coupling partners for Suzuki-Miyaura reactions.

Application

• Pharmaceutical Intermediate Synthesis: A key reagent in Suzuki-Miyaura cross-coupling reactions for constructing biaryl and heterobiaryl scaffolds found in active pharmaceutical ingredients (APIs).
• Agrochemical Development: Used in the synthesis of novel herbicides, fungicides, and insecticides that require specific phenyl-substituted structures.
• Material Science & OLEDs: Serves as a precursor for creating organic light-emitting diode (OLED) materials and other functional polymers with tailored electronic properties.
• Ligand & Catalyst Preparation: Employed in the synthesis of specialized ligands and organometallic catalysts for asymmetric synthesis and other catalytic processes.
• Chemical Biology & Probe Development: Utilized for labeling and modifying biomolecules or creating molecular probes for diagnostic applications.
• Scale-up & Process Chemistry: Its stability makes it preferable for large-scale manufacturing processes where handling and storage of traditional boronic acids is challenging.

Quality Control

Our Potassium Phenyltrifluoroborate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee reliable performance in your critical coupling reactions.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use to prevent degradation. Recommended long-term storage at 2-8°C.
