Description

Ammonium Tetraphenylborate is an organoboron salt widely used as a selective precipitating and titrimetric reagent. Its primary value lies in its ability to form insoluble complexes with large organic cations, particularly potassium and ammonium ions, enabling precise analytical determinations. This compound is essential for researchers and quality control laboratories in the pharmaceutical, chemical analysis, and academic sectors requiring high-purity reagents for ion-selective applications.

Application

• Potassium Ion Determination: A key reagent for the gravimetric and titrimetric analysis of potassium ions in various matrices, including pharmaceuticals, fertilizers, and biological fluids.
• Pharmaceutical Analysis: Used in the assay and purity testing of pharmaceutical compounds that contain potassium or other quaternary ammonium cations as counterions.
• Ion-Selective Electrodes: Serves as an active component in the membrane of ion-selective electrodes for potentiometric sensing of potassium.
• Precipitation Reagent: Employed to selectively precipitate large organic cations, alkaloids, and certain metal complexes for separation or purification purposes.
• Research & Development: Utilized in synthetic and analytical chemistry research for studying ion-pairing, phase-transfer catalysis, and as a non-coordinating anion source.
• Water Treatment Analysis: Applied in environmental testing for the determination of ammonium and potassium levels in water samples.
