Cas no 4358-26-3 (tetraphenylborate)

Sodium tetraphenylborate (NaBPh?) is an organoboron compound widely used as a precipitating agent for large cations, particularly in analytical chemistry. Its key advantage lies in its selective and quantitative precipitation of potassium, ammonium, and certain organic cations, forming insoluble tetraphenylborate salts. This property makes it valuable for gravimetric analysis, ion-selective electrodes, and phase-transfer catalysis. The compound exhibits excellent stability in aqueous and organic solvents, with low solubility in water (0.02 g/100 mL at 25°C) but good solubility in polar organic solvents like acetone and methanol. Its crystalline structure ensures high purity and reproducible results in quantitative applications. Tetraphenylborate derivatives also serve as non-coordinating anions in coordination chemistry and electrolyte systems. The reagent demonstrates consistent performance across pH ranges (2-12), maintaining reactivity without decomposing under standard conditions.
