Indole

Indole is an aromatic heterocyclic organic compound.

It naturally occurs in human feces and has an intense faecal odour. At very low concentrations though, it has a very flowery smell, and is a constituent of many floral scents (such as orange blossoms) and perfumes.

It tends to lend a "dirty" quality to a perfume.
