Luminol（Cat No.:R056846）is a chemical compound with the formula C₈H₇N₃O₂, best known for its chemiluminescent properties. When oxidized, typically in the presence of hydrogen peroxide and a catalyst like iron or copper, luminol emits a blue glow. This reaction is widely used in forensic science to detect trace amounts of blood, as hemoglobin catalyzes the luminescence. Luminol is also used in biochemical assays to study reactive oxygen species. It is a pale yellow solid in its stable form and must be activated in an alkaline solution to exhibit its signature glow.
