DPPH (2,2-Diphenyl-1-picrylhydrazyl), 98% - used as an indicator of the radical nature of that reaction. DPPH (2,2-Diphenyl-1-picrylhydrazyl) used in the quantitative determination of aliphatic and aromatic thiols by indirect spectroscopy and for photo metric determination of tocopherol. DPPH (2,2-Diphenyl-1-picrylhydrazyl) 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. DPPH is a well-known radical and a trap ("scavenger") for other radicals.

Description

DPPH is a common abbreviation for an organic chemical compound 2,2-diphenyl-1-picrylhydrazyl. DPPH (2,2-Diphenyl-1-picrylhydrazyl) is a free radical, which shows hydrogen accept or ability towards antioxidants.
