In organic chemistry, indoxyl is a nitrogenous substance with the chemical formula: C8H7NO.[1][2] Indoxyl is isomeric with oxindol and is obtained as an oily liquid.
Indoxyl is obtained from indican, which is a glycoside. The hydrolysis of indican yields β-D-glucose and indoxyl.
Indigo dye is a product of the reaction of indoxyl with a mild oxidizing agent such as atmospheric oxygen.
Indoxyl can be found in urine and is titrated with Obermayer's reagent, which is a dilute solution of ferric chloride (FeCl3) in hydrochloric acid (HCl).[3]
