Alizarin Red S (also known as C.I. Mordant Red 3, Alizarin Carmine, and C.I 58005.[1]) is a water-soluble sodium salt of Alizarin sulfonic acid with a chemical formula of C
14H
7NaO
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]

Uses

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]
