|Use|| Alizarin Red is used in a biochemical assay to determine, quantitatively by colorimetry, the presence of calcific deposition by cells of an osteogenic lineage. As such it is an early stage marker (days 10–16 of in vitro culture) of matrix mineralization, a crucial step towards the formation of calcified extracellular matrix associated with true bone.

Brief manufacture process:
The alizarin added 15% fuming sulfuric acid, 105-110 ° C sulfonation, heat 3h, cooling, pouring into distilled water, 60 ° C sodium chloride precipitation, heated to 70 ° C, placed overnight, filtration. After washing with 10% sodium chloride solution, it was dissolved in steam
Distilled water, placed, filtered. The solution was soaked in ethanol and hydrochloric acid (9: 1). The crystals were stirred overnight, and the crystals were dried at 80 ° C or lower. Purification: alizarin red by water dissolved in hot water, coupled with activated carbon decolorization, filtration, while stirring the filtrate plus ammonia, until a small amount of crystalline precipitation, stirring 20min, placed overnight, filtration, the product at 70-80 ℃ dry.
