1,1-Diphenyl-2-Picrylhydrazyl (DPPH) is a widely used stable free-radical reagent for the quantitative evaluation of antioxidant activity. It is commonly applied in the DPPH radical scavenging assay, where antioxidants reduce the deep violet color of DPPH to a pale yellow form, enabling easy spectrophotometric measurement. Bright Scientific offers high-purity DPPH reagent that ensures accurate, reproducible, and reliable results. It is suitable for routine laboratory analysis as well as advanced research applications in pharmaceutical, food, and life science laboratories. Key Features High-purity laboratory and research-grade reagent Stable free-radical compound with excellent shelf stability Provides consistent and reproducible assay results Easy to dissolve in common organic solvents Suitable for academic, research, and industrial laboratories Applications Antioxidant activity determination DPPH free-radical scavenging assay Pharmaceutical research and formulation studies Food, nutraceutical, and natural product analysis Biochemistry and life science research Quality control and academic laboratory experiments Chemical Information Chemical Name: 1,1-Diphenyl-2-Picrylhydrazyl Common Name: DPPH Molecular Formula: C₁₈H₁₂N₅O₆ Molecular Weight: ~394.32 g/mol Appearance: Dark violet crystalline powder Solubility: Soluble in methanol, ethanol, and organic solvents Grade: Laboratory / Research Grade Storage & Handling Store in a cool, dry, and well-ventilated place Keep container tightly closed when not in use Protect from light and moisture For laboratory use only; handle using standard safety precautions Why Buy from Bright Scientific?
