Superoxide scavenger with neuroprotective, anti-inflammatory and analgesic effects4-Hydroxy-TEMPO free radical is used as a catalyst and a chemical oxidant by virtue of being a stable radical. It is used for detoxifying reactive oxygen species in medicinal chemistry. It is involved in the catalysis of disproportionation of superoxide and facilitates hydrogen peroxide metabolism. It is used to prepare tris(2,2,6,6-tetramethyl-1-oxyl-4-piperidyloxy)trimellitate by reacting with benzene-1,2,4-tricarbonyl trichloride. Further, it is used as a free radical scavenger and exhibits neuroprotective, anti-inflammatory and analgesic effects. In addition to this, it has good inhibition effect to acrylic acid esters, methyl acrylate, acrylic acid, acrylonitrile, styrene and butadiene.
