Tetrabutyl Ammonium Hydrogen Sulphate (TBHS) (CAS NO : 32503-27-8)

Tetrabutylammonium hydrogen sulfate (CAS No: 32503-27-8) serves as a premier phase-transfer catalyst (PTC) in the specialty chemicals market, facilitating complex multi-phase organic synthesis by enabling the migration of anions from aqueous to organic layers for streamlined alkylations and oxidations. Beyond its catalytic prowess, this quaternary ammonium salt is indispensable as a high-precision ion-pairing reagent in reversed-phase liquid chromatography (RPLC), where it enhances the resolution of polar and ionizable pharmaceutical compounds. The compound is increasingly integrated into advanced electrochemical applications and surfactant formulations, leveraging its ability to lower surface tension and enhance electrolyte conductivity in high-performance industrial coatings and energy storage systems.
