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 certain ammonium ions, making it indispensable for analytical and research applications. This compound is essential for laboratories and industries involved in pharmaceutical analysis, ion-selective electrode manufacturing, and advanced materials research.

Application

• Analytical Chemistry Reagent: Used for the gravimetric determination and titration of potassium, rubidium, cesium, and large organic cations like alkaloids and quaternary ammonium salts.
• Pharmaceutical Analysis: Employed in the assay and purity testing of active pharmaceutical ingredients (APIs) that contain cationic functional groups.
• Sensor & Electrode Manufacturing: Serves as a key ionophore component in the membrane of ion-selective electrodes (ISEs) for potassium detection.
• Research & Development: Utilized in organic synthesis and materials science as a precipitating agent or a source of tetraphenylborate anion for creating novel ionic compounds.
• Quality Control Laboratories: Applied in standard methods for the quantitative analysis of cationic surfactants and other ionic species in industrial products.
