Description

Other Notes

Same product — same quality — now Sigma-Aldrich brand

Application

TBAHS was suitable as ion-pairing reagent in determination and separation of thallium using ionic liquid-assisted ion-pairing liquid-liquid microextraction and inductively coupled plasma mass spectrometry. It was suitable as mobile phase component for a HPLC-UV analysis to quantify chondroitin sulfate.

General description

Tetrabutyammonium bisulfate (TBAHS) is an ion-pairing reagent. It acts as a catalyst in hydrolysis of aziridines and epoxides and the catalyst can be recycled.
