Indoxyl
pale yellow crystals with an unpleasant odor; melting point, 85°C. The substance exists in two tautomeric forms:
Indoxyl is present in the urine of human beings and animals as the potassium salt of 3-indoxyl sulfuric acid (urinary indican) and in the juices of certain tropical plants (in the form of glycosides), from which it can be obtained by hydrolysis.
Indoxyl is an important intermediate product in the synthesis of indigo, a dye formed during the oxidation of indoxyl. Reduction of indoxyl yields indole.
