Luminol, 1 g, Powder

Luminol powder's chemical formula is C₈H₇N₃O₂, and it is an essential component to any crime scene or chemiluminescence investigation. This 1 gram quantity is plenty to make a luminol solution for forensic blood detection experiments, or to explore chemiluminescence using a small number of additional chemicals.

To see luminol shine, mix it with dilute sodium hydroxide, and add 3% hydrogen peroxide and a catalyst (like potassium ferricyanide). When used for blood detection, the iron in the hemoglobin replaces the potassium ferricyanide catalyst - resulting in a glowing reaction.
