Indole (CAS NO.120-72-9) can be used to produce isatin and oxindole. Oxindole was reduced to indole using zinc dust by Adolf von Baeyer In 1866. Then in 1869, Adolf von Baeyer give a formula for indole.Until the end of the 19th century,one kind of indole derivatives was important dyestuffs. Later, In the 1930s, people found that the indole nucleus is present in many important alkaloids. It plays an important role in today research work.
Indole (CAS NO.120-72-9) is used in Natural jasmine oil. Natural jasmine oil is used in the perfume industry which contains about 2.5% of indole. Besides,Indole is used in the manufacture of synthetic jasmine oil.
Method of synthesis of Indole (CAS NO.120-72-9): Leimgruber-Batcho indole synthesis; Fischer indole synthesis; Bartoli indole synthesis; Bischler-M?hlau indole synthesis; Fukuyama indole synthesis; Gassman indole synthesis; Hemetsberger indole synthesis; Larock indole synthesis; Madelung synthesis; Nenitzescu indole synthesis; Reissert indole synthesis; Baeyer-Emmerling indole synthesis
