CYPMPO是用于电子自旋共振（ESR）自由基自旋捕集的溶剂。使用CYPMPO的一个优点是它显示出对捕获超氧化物和羟基自由基的偏爱。研究表明，由于难溶性和形成不稳定的加合物，亲脂性抗氧化剂很难捕获自由基的ESR。CYPMPO是有利的，因为它可以形成稳定的加合物，这些加合物在ESR中清晰可辨。此外，由于其低毒性，CYPMPO在生物和化学系统中是有效的。 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.
