Alizarin has a major application in the manufacture of the madder lake pigments which is commonly called as Rose madder and Alizarin crimson. It is involved in the studies of bone growth, osteoporosis, bone marrow and calcium deposits in the vascular system. It is also used as a stain in calcite and aragonite to identify calcium carbonate, and synovial fluid to asses for basic calcium phosphate crystals. It is used in colorimetric measurements for quantification of amine extraction by model food simulants from epoxy polymer.
