일반 설명

2,2-diphenyl-1-picrylhydrazyl is a free radical, which shows hydrogen acceptor ability towards antioxidants. Hence, it is commonly used in DPPH assay for measuring the antioxidant activity of different natural samples such as wine, fruits, herbal tea etc.

애플리케이션

Stable p-radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) adsorbed at the elbows of 22×3 reconstructed Au (111): This study focuses on the single-molecule level investigation of the stable organic radical DPPH, exploring its adsorption and interaction characteristics on a gold surface, which is crucial for understanding metal-free magnetic phenomena at subnanometer scales (R Vranik et al., 2020).
