Inorganic chemistry,indoxyl is anitrogenous substance with thechemical formula: C₈H₇NO.^[1][2] Indoxyl isisomeric withoxindol and is obtained as an oily liquid.

TheHeumann indigo synthesis starts fromanthranilic acid:

In nature indoxyl is derived fromindican, which is aglycoside. Thehydrolysis ofindican yields β-D-glucose and indoxyl.

Indigo dye is a product of the mildoxidation of indoxyl.

Indoxyl can be found in urine and is titrated with Obermayer's reagent, which is a dilute solution offerric chloride (FeCl₃) inhydrochloric acid (HCl).^[3]
