TEMPO (Cat No.:R058813) is a stable nitroxyl radical widely used as a catalyst and oxidizing agent in organic synthesis. Its persistent free radical nature makes it ideal for selective oxidation of alcohols to aldehydes or ketones, especially in aerobic or metal-catalyzed systems. TEMPO is a red-orange crystalline solid, highly soluble in organic solvents, and thermally stable. Beyond oxidation chemistry, it is used in polymer chemistry, spin labeling, and as a mediator in controlled radical polymerization. Its mild reaction conditions and selectivity contribute to its popularity in green and sustainable chemical processes.
