Indoxyl
Indoxyl, also known as 1H-indol-3-ol, belongs to the class of organic compounds known as hydroxyindoles. These are organic compounds containing an indole moiety that carries a hydroxyl group. Indoxyl is isomeric with oxindol and is obtained as an oily liquid. Indoxyl exists in all living organisms, ranging from bacteria to humans. Indoxyl is obtained from indican, which is a glycoside. Obermayers reagent is a dilute solution FeCl3 in hydrochloric acid. The hydrolysis of indican yields β-D-glucose and indoxyl. Indigo dye is a product of the reaction of indoxyl by a mild oxidizing agent such as atmospheric oxygen. In chemistry, indoxyl is a nitrogenous substance with the chemical formula: C8H7NO. Indoxyl can be found in urine and is titrated with Obermayers reagent. Indigo dye is a product of the reaction of indoxyl by a mild oxidizing agent, eg. atmospheric oxygen.
