Description and Uses

5,6-Dihydroxyindole is a melanin precursor. It is one of the toxic compounds in the melanin biosynthetic pathway. 5,6-Dihydroxyindole is an indole derivative that contains two hydroxyl groups attached to the 5th and 6th positions of the indole ring. It is an intermediate in the biosynthesis of melanin, a pigment responsible for the coloration of hair, skin, and eyes in humans and other organisms.

5,6-Dihydroxyindole is an intermediate in melanogenesis, the production of melanin which is found in our skin, eyes, hair, and inner ear.
