Description

Potassium Trifluoro(neopentyl)borate (CAS: 1150655-02-9) is a highly specialized organoboron compound with the molecular formula C₅H₁₁BF₃K. This potassium salt of trifluoro(neopentyl)borate is a versatile reagent widely used in synthetic chemistry, particularly in cross-coupling reactions, due to its stability and reactivity. The neopentyl (2,2-dimethylpropyl) group enhances steric hindrance, making it valuable for selective transformations in organic synthesis.

This high-purity compound is ideal for researchers and scientists working on polymer chemistry, pharmaceutical intermediates, and advanced material science. It is supplied as a white to off-white crystalline powder with stringent quality control to ensure consistency in performance. Store in a cool, dry place under inert conditions to maintain stability.

Key Features:

• High reactivity in Suzuki-Miyaura and other palladium-catalyzed cross-coupling reactions
• Excellent solubility in polar aprotic solvents (e.g., DMF, DMSO)
• Stable under inert atmospheres with minimal decomposition
• Strictly controlled moisture levels (<1%) for optimal performance
