4-Hydroxy-2,2,6,6-tetramethylpiperidinooxy, commonly abbreviated as 4-Hydroxy-TEMPO or simply TEMPOL, is a stable nitroxyl radical and a derivative of the piperidine family. It is widely used as a radical scavenger, an antioxidant, and in various chemical and biological applications.

Chemical Structure and Properties

Chemical Formula: C9H18NO2
Molecular Weight: 172.25 g/mol
Structure: The chemical structure of 4-Hydroxy-TEMPO consists of a piperidine ring substituted with four methyl groups at the 2, 2, 6, and 6 positions, a hydroxyl group (-OH) at the 4th position, and a nitroxyl radical (N-O•).
Appearance: It typically appears as an orange to red crystalline solid.
Solubility: Soluble in organic solvents like ethanol, methanol, and chloroform; slightly soluble in water.
Stability: As a stable nitroxyl radical, 4-Hydroxy-TEMPO is relatively stable under normal conditions but should be protected from excessive light and heat.
