Description and Uses

Indole has an almost floral odor when highly purified. Otherwise, it exhibits the characteristic odor of feces. It is not very stable on exposure to light (turns red). Indole may be obtained from the 220 - 260°C boiling fraction of coal tar or by heating sodium phenylglycine-o-carboxylate with NaOH, saturating the aqueous solution of the melt with C 02, and finally reducing with sodium amalgam; can be prepared also by the reduction of indoxyl, indoxyl carboxylic acid, or indigo.

Can be used in perfumes and in the synthesis of tryptophan.
