◉ product description

Tetrabutylammonium Hydroxide CAS#2052-49-5

At room temperature, it is a white crystalline powder with a fine crystal structure. It is hygroscopic and readily deliquesces into a paste when exposed to air. Due to the extremely strong hygroscopicity of pure products, they are mostly supplied in the form of aqueous solutions or alcohol solutions (such as methanol and ethanol solutions) in industry, with concentrations typically ranging from 10% to 50%.

Product Usage

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