CAS 2564-83-2: Tempo

Description: Tempo, or 2,2,6,6-tetramethylpiperidinyl-1-oxyl, is a stable free radical characterized by its distinctive structure, which includes a piperidine ring and a nitroxide functional group. This compound is known for its stability and ability to act as a radical scavenger, making it useful in various applications, including organic synthesis and polymer chemistry. Tempo exhibits a characteristic deep yellow color and is soluble in organic solvents such as ethanol and acetone, but it is less soluble in water. Its radical nature allows it to participate in redox reactions, and it is often employed as a spin label in electron paramagnetic resonance (EPR) spectroscopy. Additionally, Tempo can serve as an oxidation catalyst in certain chemical reactions, enhancing the efficiency of processes such as the oxidation of alcohols to carbonyl compounds. Its unique properties make it a valuable tool in both academic research and industrial applications.
