Description

General description

Tetrabutylammonium hydroxide (TBAOH) is a quaternary ammonium salt,mainly used as a strong base and phase-transfer catalyst.

Application

TBAOH may be used as an ion-pairing reagent in mobile phase preparation for reverse phase ion-pair high performance liquid chromatography during chromium (III) and chromium (VI) determination.

Caution

may crystallize; can be redissolved on heating (max. 40°C)
