Description

Potassium sec-Butyltrifluoroborate is an organoboron reagent widely used as a key building block in modern synthetic chemistry. This compound matters for its role as a stable, air- and moisture-tolerant precursor in Suzuki-Miyaura cross-coupling reactions, enabling the efficient construction of complex organic molecules. It is primarily needed by research and development laboratories, pharmaceutical intermediates manufacturers, and agrochemical producers for creating novel compounds and fine chemicals.

Application

• Suzuki-Miyaura Cross-Coupling Reactions: A critical reagent for forming carbon-carbon bonds between aryl/vinyl halides and the sec-butyl group.
• Pharmaceutical Intermediate Synthesis: Used in the development and scale-up of active pharmaceutical ingredients (APIs) requiring sec-butyl motifs.
• Agrochemical Research: Employed in the synthesis of novel herbicides, fungicides, and insecticides with tailored properties.
• Material Science: Serves as a precursor for creating functionalized polymers and advanced organic materials.
• Ligand and Catalyst Development: Utilized in the preparation of specialized ligands and organometallic catalysts.
• Academic and Industrial R&D: A staple in research laboratories for methodological development and exploring new synthetic pathways.

Quality Control

Our Potassium sec-Butyltrifluoroborate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR (1H, 11B, 19F) and HPLC analysis, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are available upon request to support your quality assurance protocols.

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 product performance. Keep away from incompatible materials.
