Description

CYPMPO is a solvent used in electron spin resonance (ESR) free radical spin trapping. One advantage to using CYPMPO is that it shows preference for trapping superoxide and hydroxyl radicals. Studies indicate that ESR trapping of free radicals is very difficult on lipophilic antioxidants as a result of poor solubility and formation unstable adducts. CYPMPO is favorable because it can form stable adducts that are clearly separated and identifiable in ESR. Furthermore, CYPMPO is efficient in biological and chemical systems because of its low toxicity.
