Product Name:2,2,6,6-Tetramethylpiperidine-1-oxyl
English Name:2,2,6,6-Tetramethylpiperidine-1-oxyl
CAS No.:2564-83-2
Aliases:TEMPO, 2,2,6,6-Tetramethylpiperidinooxy
Molecular Formula:C9H18NO
Physical Properties:Molecular weight: 156.25. Appearance: orange to red crystalline solid or powder, slight color variation depending on purity. Melting point: 36–38 °C. Boiling point: approximately 175–193 °C (decomposes). Relative density: approximately 0.912–1.0 g/cm³. Flash point: approximately 68 °C. Vapor pressure: 0.4 hPa (20 °C). Refractive index: 1.4350. Soluble in most organic solvents such as methanol, ethanol and benzene; slightly soluble or insoluble in water. Stable at room temperature; unstable in the presence of strong acids or strong oxidants.
Uses:Used as a highly efficient and selective oxidation catalyst for converting primary alcohols to aldehydes and secondary alcohols to ketones in combination with co-oxidants, widely applied in the synthesis of pharmaceutical intermediates and fine chemicals. As a radical scavenger, it serves as a polymerization inhibitor and stabilizer, and is also employed in nitroxide-mediated polymerization (NMP) to produce polymers with narrow molecular weight distribution. Additionally, it acts as a light and heat stabilizer in plastics and rubber.
