compound introduction
2,2-二苯基-1-苦基肼是一种对抗氧化剂显示出氢受体能力的自由基。因此，它常用于测量不同天然样品如酒、水果、凉茶等抗氧化活性的DPPH检测。 2,2-Diphenyl-1-picrylhydrazyl is used as a sensitive colorimetric free radical scavenger. It serves as a general antioxidant detector. It is utilized to monitor chemical reactions involving radicals as well as a standard of the position and intensity of electron paramagnetic resonance signals. Further, it is employed in the quantitative determination of aliphatic and aromatic thiols by indirect spectroscopy and for photometric determination of tocopherol.
