3,3,5,5-Tetramethyl-1-pyrroline 1-oxide - Reference Information

Introduction

3,3,5, 5-tetramethyl-1-pyrroline-N-oxide is a spin trapping reagent. As a simple and effective method, electron spin resonance capture technology is widely used to monitor active free radicals. Five-membered nitrone spin trapping agents can effectively capture and identify many types of active free radicals, especially oxygen free radicals.
