chemical property: orange-red powder or crystals
Uses Indigo and its derivatives as indigo and related dyes and some of the raw materials for the preparation of drugs. Because of its hepatotoxicity, indigo derivatives are no longer used in the pharmaceutical industry. A precipitant for the detection of ketones and silver. Spectrophotometric Determination of Thiophene, Thiol, Thiophene, Urine Blue and Proline.
Preparation Source By indophenol or indigo by oxidation and prepared. Indigo was first isolated by the French chemist Auguste Laurent. In 1878, Adolf von Bayer completed the full synthesis of isatin. In 1880, Bayer developed a method of synthesizing isatin from o-nitrocinnamic acid. In 1883, from the o-nitrobenzaldehyde synthesis of isatin method by Bayer patent. Since then, indigo as the raw material for the synthesis of indigo gradually replace the method of extraction from plants, as the main source of indigo.
