Alizarin Usage And Synthesis
Chemical Propertiesorange-red crystals or powder
HistoryIn ancient times, alizarin was the preferred red dye. Cloth dyed with it has been found in Egyptian tombs dating 6000 years ago. The dye is found in the madder plant, a member of the Rubiaceae family. In 1944 about 35 species of this plant were known, but the use of more sophisticated analytical methods led to the detection of many more species; by 1984 the number had increased to 50. Alizarin is a mordant dye forming various colored coordination complexes with different metallic salts.
Usesantimutagen
UsesAlizarin is used widely as a prominent red dye for textile facbrics. Alizarin red is now used in biochemical assay to determine quantitatively by colorimetry, the presence of calcific deposition by ce lls of the osteogenic lineage. Alzarine derivatives was evaluated as new inhibitors of the HIV-1 reverse transcriptase associated DNA polymerase and RNase H. Alizarin was also shown to inhibit prolife ration, tumor growth and suppress tumorigenesis in human osteosarcoma and breast cancer cell representative for bone metastasis.
DefinitionChEBI: A dihydroxyanthraquinone that is anthracene-9,10-dione in which the two hydroxy groups are located at positions 1 and 2.
DefinitionAn important orange-red organic compound used in the dyestuffs industry to produce red lakes. It occurs naturally in the root of the plant madder and may also be synthesized from anthraquinone.
Definitionalizarin: An orange-red compound,C14H8O4. The compound is a derivativeof anthraquinone, with hydroxylgroups substituted at the 1and 2 positions. It is an importantdyestuff producing red or violetlakes with metal hydroxide.Alizarin occurs naturally as the glucosidein madder. It can be synthesizedby heating anthraquinone withsodium hydroxide.
Purification MethodsAlizarin crystallises from glacial acetic acid or 95% EtOH. It can also be sublimed at 110o/2mm. It is an indicator with max at 452nm (pH 5.8) and 520nm (pH 7.2). [Beilstein 8 IV 3256.]
