7S. [2] [1] Alizarin Red S was discovered by Graebe and Liebermann in 1871. [2] In the field of histology alizarin Red S is used to stain calcium deposits in tissues, [3] [4] and in geology to stain and differentiate carbonate minerals. [3]

Alizarin Red S, as sold for use as a histologic stain.

Alizarin Red S is used in histology and histopathology to stain, or locate calcium deposits in tissues. [1] [3] [4] In the presence of calcium, Alizarin Red S, binds to the calcium to form a Lake pigment that is orange to red in color. [4] Whole specimens can be stained with Alizarin Red S to show the distribution of bone, especially in developing embryos. [4] In living corals alizarin Red S has been used to mark daily growth layers. [5]

In geology, Alizarin Red S is used on thin sections, and polished surfaces to help identify carbonate minerals which stain at different rates. [6]
