General Description

The chemical 2,5-bis[(2-ethoxyphenyl)amino]-3,6-dimethoxycyclohexa-2,5-diene-1,4-dione, also known as DPPH, is a stable free radical commonly used in antioxidant assays. It is a dark purple crystalline powder with a characteristic absorption peak at 517 nm. DPPH is widely used to measure the antioxidant activity of various compounds, including natural products and synthetic antioxidants. It works by reacting with antioxidant compounds and producing a colorless product, which can be measured spectrophotometrically. DPPH is a valuable tool for assessing the antioxidant potential of different substances and understanding their ability to neutralize free radicals and protect against oxidative stress.
