Notes: DTUN is a lipophilic hyponitrite radical initiator.{54815} It initiates co-autoxidation of STY-BODIPY-embedded egg phosphatidylcholine liposomes when used at a concentration of 0.2 mM. DTUN has been used in fluorescence-enabled inhibited autoxidation (FENIX) assays for the development of ferroptosis inhibitors and the study of antioxidants in lipid membranes.{54815,59240}
