Tetrabutylammonium Hydrogen Sulfate
Exceptional Catalytic Performance: Functions as a highly efficient phase-transfer catalyst to substantially accelerate reaction kinetics.
Chromatographic Applications: Commonly employed as a buffer salt component in reversed-phase liquid chromatography systems.
Enhanced Analytical Accuracy: Contributes to improved separation efficiency and detection reliability in analytical methods.
Dual-Function Versatility: Suitable for applications spanning chemical synthesis processes and analytical testing methodologies.
Tetrabutylammonium Hydrogen Sulfate function as highly efficient phase transfer catalysts. The tetrabutylammonium hydrogen sulfate buffer system is frequently utilized as an aqueous mobile phase in reversed-phase liquid chromatography. It should be noted that the stability of this buffer solution decreases progressively with increasing salt concentration. For optimal performance, the buffer requires fresh preparation before each application and should be used within 6 hours. When stored at room temperature for approximately 8 hours, visible turbidity may develop, potentially causing chromatographic peak drift and salt crystallization in the pumping system or separation column, which could result in significant instrument damage.
