DPPH

2,2-Diphenyl-1-picrylhydrazyl (DPPH) is a stable free radical and colorimetric probe for the detection of free radical scavengers. Upon reaction with antioxidants, DPPH turns from deep violet to yellow, which can be quantified by colorimetric detection at 515 nm as a measure of antioxidant capacity. DPPH has commonly been used to measure the antioxidant potential of plant extracts, foodstuffs, and pure compounds.Formal Name: 2,2-diphenyl-1-(2,4,6-trinitrophenyl)-hydrazinyl.
