Description

Potassium (3-(tert-Butyl)-1H-Pyrazol-5-Yl)Trifluoroborate is a valuable organotrifluoroborate salt, a stable and versatile reagent in modern synthetic chemistry. Its primary value lies in its role as a robust coupling partner in Suzuki-Miyaura cross-coupling reactions, enabling the efficient construction of complex molecules. This compound is essential for researchers and process chemists in the pharmaceutical, agrochemical, and advanced materials industries who require reliable, air- and moisture-stable intermediates for constructing pyrazole-containing scaffolds.

Application

• Pharmaceutical Intermediate: A key building block for the synthesis of active pharmaceutical ingredients (APIs) containing the 3-(tert-butyl)-1H-pyrazole moiety.
• Agrochemical Synthesis: Used in the research and production of novel herbicides, fungicides, and insecticides that incorporate pyrazole heterocycles.
• Suzuki-Miyaura Cross-Coupling: Serves as a stable, easy-to-handle boronic acid equivalent for palladium-catalyzed carbon-carbon bond formation under mild conditions.
• Ligand and Catalyst Development: Employed in the preparation of novel pyrazole-based ligands for catalysis and metal-organic frameworks (MOFs).
• Material Science Research: A precursor for creating functional organic molecules used in electronic materials and organic light-emitting diodes (OLEDs).
• Chemical Biology Probes: Useful for synthesizing tagged molecules and probes for studying biological systems and drug discovery.

Quality Control

Our Potassium (3-(tert-Butyl)-1H-Pyrazol-5-Yl)Trifluoroborate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR (1H, 13C, 19F, 11B) and HPLC analysis, to ensure high chemical purity and identity. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided with every shipment to guarantee consistency and support your research and development needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) due to its hygroscopic (moisture-sensitive) nature. Allow the container to reach room temperature before opening to minimize moisture ingress.
