Description Application Tetrabutylammonium chloride (TBAC) hydrate has been used as a phase transfer catalyst in the synthesis of fullerenols and in Heck-type palladium-catalyzed vinylation of organic halides in water. TBAC hydrate has also been reported to be a promising candidate for cool energy storage material. Tetrabutylammonium chloride hydrate can be used: • As an additive in palladium-catalyzed cross-coupling reaction of heteroaromatic carboxylic acids with aryl bromides. • To enhance the reactivity of palladium-catalyzed arylation of methyl acrylates. • In derivatization of bis(spirodienone) calixarene having exocyclic double bonds to its chloro derivative. Packaging 5, 25, 100 g in glass bottle
