Carmine (1390-65-4, 1260-17-9, 1343-78-8)  
carminic acid  ·  Cochineal Dye  ·  Natural Red 4
Carminic acid (C22H20O13) is a red glucosidal hydroxyanthrapurin that occurs naturally in some scale insects, such as the cochineal, Armenian cochineal, and Polish cochineal. The insects produce the acid as a deterrent to predators. An aluminum salt of carminic acid is the coloring agent in carmine.
