DPPH

Also known as 2,2-diphenyl-1-(2,4,6-trinitrophenyl)hydrazin-1-yl, DPPH radical

DPPH (2,2-diphenyl-1-picrylhydrazyl) is an organic chemical compound. It is a dark-colored crystalline powder composed of stable free radical molecules. DPPH has two major applications, both in laboratory research: one is a monitor of chemical reactions involving radicals, most notably it is a common antioxidant assay, and another is a standard of the position and intensity of electron paramagnetic resonance signals.
