A synthetic form of alizarin (1,2-dihydroxyanthraquinone) was first made in 1868 by Carl Graebe and Carl Lieberman, from [[anthracene|anthracene]], a coal tar product.

Description
A synthetic form of alizarin (1,2-dihydroxyanthraquinone) was first made in 1868 by Carl Graebe and Carl Lieberman, from Anthracene, a coal tar product. Prior to that time, alizarin was obtained from the root of the madder plant, Rubia tinctorum L.. The orthorhombic, orange-red crystals of alizarin appear brownish-yellow in powder form. Alizarin is most commonly used for the derivatization of other dyes, but it is also known as a textile dye, a pigment, and an indicator. To prepare alizarin crimson pigment, alizarin is precipitated on a neutral base of Alumina trihydrate producing a brilliant, transparent color that has fair to good permanency. Alizarin will turn blue to purple in basic aqueous solutions, but it is more often used as an acid-base indicator in alcoholic solutions (0.5%) where it changes from yellow at pH 5.5 to red at pH 6.8. Alizarin is also used in spot tests as a reagent for [aluminum|aluminum]], Indium, Mercury, Zinc, and Zirconium. As a textile dye, the cloth (Cotton, Wool, or Silk) must be mordanted with a metal oxide. The shade produced depends on the metal present: aluminum yields a red; iron, a dark violet; and Chromium, a reddish-brown.
