Indole

Indole is a white to pale yellow crystalline solid with a characteristic fecal odor at high concentrations, though it exhibits a floral scent (reminiscent of jasmine) at low dilutions. It is an aromatic heterocyclic organic compound, featuring a fused benzene and pyrrole ring system, with a melting point of 52–54 °C and a boiling point of 253–254 °C. Indole serves primarily as a versatile chemical intermediate in the synthesis of fine chemicals and specialty compounds.
