Description

Potassium 7-Quinolinetrifluoroborate is an organoboron reagent belonging to the potassium trifluoroborate salt family, a valuable class of air- and moisture-stable coupling partners. This compound is a crucial synthetic intermediate, prized for its enhanced stability and handling properties compared to boronic acids in cross-coupling reactions. It is primarily utilized by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials industries for constructing complex heterocyclic scaffolds.

Application

• Suzuki-Miyaura Cross-Coupling Reactions: A stable, shelf-stable alternative to boronic acids for forming carbon-carbon bonds with aryl/heteroaryl halides.
• Pharmaceutical Intermediate Synthesis: Key building block for the development of active pharmaceutical ingredients (APIs) containing the quinoline moiety.
• Agrochemical Research: Used in the synthesis of novel herbicides, fungicides, and insecticides with complex heterocyclic structures.
• 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 novel nitrogen-containing ligands for transition metal catalysis.
• Chemical Biology & Probe Development: Useful for creating fluorescent probes or bioconjugates based on the quinoline fluorophore.

Quality Control

Our Potassium 7-Quinolinetrifluoroborate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity for demanding synthetic applications. Each lot is characterized by NMR (1H, 13C, 19F, 11B) and HPLC analysis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory documentation.

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 reactivity. For long-term storage, consider using desiccants.
