Luminol (C8H7N3O2) is a versatile chemical that exhibits chemiluminescence, with a striking blue glow, when mixed with an appropriate oxidizing agent.
It is a white to slightly yellow crystalline solid that is soluble in most polar organic solvents, but insoluble in water.
Luminol is used by forensic investigators to detect trace amounts of blood left at crime scenes as it reacts with iron found in hemoglobin.
It is used by biologists in cellular assays for the detection of copper, iron, and cyanides, in addition to the detection of specific proteins by Western Blot.
