Description

Potassium (3,4-Dichlorophenyl)Trifluoroborate is a high-purity organotrifluoroborate salt, a crucial building block in modern synthetic chemistry. Its primary value lies in its exceptional stability and reactivity as a key coupling partner in Suzuki-Miyaura cross-coupling reactions. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials industries who require reliable, high-quality intermediates for constructing complex aromatic and heteroaromatic systems.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those containing complex biaryl or heterobiaryl motifs.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and insecticides that require specific chlorinated phenyl structures.
• Material Science Research: Serves as a building block for creating novel organic electronic materials, ligands for catalysts, and liquid crystals.
• Cross-Coupling Reactions: An air- and moisture-stable alternative to boronic acids in palladium-catalyzed Suzuki-Miyaura couplings, enabling efficient carbon-carbon bond formation.
• Chemical Library Development: Employed in medicinal and combinatorial chemistry for the rapid generation of diverse compound libraries for screening.
• Custom Synthesis & Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for bespoke synthesis projects.
