Allgemeine Beschreibung

Tetraethylammonium hydroxide (TEAOH) is a quaternary ammonium salt that is commonly used as a strong base and phase-transfer catalyst in organic synthesis.

Anwendung

Tetraethylammonium hydroxide (25% in methanol) can be used as a base in the synthesis of 2-hydroxyacetophenoxime from 2-hydroxysalicylaldoxime and hydroxylamine hydrochloride. It is also used as an organic structure-directing agent in the synthesis of zeolites such as Beta, ZSM-20, and SAPO-34.

Evidence has indicated that resveratrol (Res) produces vasorelaxation and may decrease the coronary heart disease mortality. However, several pathways involved in the mechanism of vasorelaxation are still unclear. This study was designed, therefore, to test the probable ion channels or
