4-Oxo-TEMPO Chemical Properties,Usage,Production

Description

2,2,6,6-Tetramethylpiperidin-1-oxyl (TEMPO) is a stable radical that will react with reactive oxygen species (ROS). This conversion, followed by ESR, provides an indirect way to monitor ROS production in biological systems. TEMPONE is the 4-oxo derivative of TEMPO. In addition to possible uses as a spin trap, this nitroxyl radical can be used in hydrogen transfer experiments and as a polarizing agent in dynamic nuclear polarization NMR spectroscopy. TEMPONE and other nitroxyl radicals have also been shown to reduce mean arterial pressure in spontaneously hypertensive rats when administered intravenously.

Chemical Properties

Pink Needles

Uses

A spin label for ESR studies

Uses

Free-radical nitroxide spin probe typically used for:

Redox sources for anodes in lithium secondary batteries
Free-radical biological studies
Radical spin-trapping
Electron paramagnetic resonance studies
Polymer chemisty and synthesis applications

General Description

4-Oxo-TEMPO is formed by the reaction of 2,2,6,6-tetramethyl-4-piperidone (4-oxo-TMP) and ¹O₂. It is a stable paramagnetic product formed during the irradiation of TiO₂ in aqueous suspensions.

Flammability and Explosibility

Non flammable
