Product Name:Potassium 1H-pyrazole-5-trifluoroborate
English Name:Potassium 1H-pyrazole-5-trifluoroborate
CAS No.:1013640-87-3
Aliases:Pyrazole-5-trifluoroborate potassium salt, Potassium (1H-pyrazol-5-yl)trifluoroborate
Molecular Formula:C3H3BF3KN2
Physical Properties:White to off-white crystalline powder. Molecular weight 173.97, melting point approximately 250°C (decomposition). Readily soluble in polar organic solvents (e.g., DMF, DMSO, acetonitrile), slightly soluble in water, insoluble in non-polar solvents. Relatively stable to air and moisture, but should be stored sealed and protected from light.
Uses:Used as a potassium trifluoroborate reagent in organic synthesis, particularly applicable to Suzuki-Miyaura cross-coupling reactions as a substitute for boronic acids or boronate esters in carbon-carbon bond formation. This compound offers excellent stability and reaction selectivity, and is commonly employed in the synthesis of biaryl compounds, nitrogen-containing heterocycles, and pharmaceutical intermediates.
Technical Specifications:
Purity: ≥98% (HPLC)
Appearance: white to off-white crystalline powder
Molecular weight: 173.97
Storage: keep sealed at 2-8°C, protected from light
Solubility: freely soluble in DMF and DMSO, slightly soluble in water
