Indole

Indole has an unpleasant odor at high concentration, odor becomes floral at higher dilutions white crystals with an unpleasant odourindole: A yellow solid, C8H7N, m.p.52°C. Its molecules consist of a benzenering fused to a nitrogen-containingfive-membered ring. It occurs insome plants and in coal tar, and isproduced in faeces by bacterial action.It is used in making perfumes.Indole has the nitrogen atom positionednext to the fused benzenering.
Indole is an aromatic heterocyclic organic compound with formula C8H7N. It has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered nitrogen-containing pyrrole ring. Indole is widely distributed in the natural environment and can be produced by a variety of bacteria. As an intercellular signal molecule, indole regulates various aspects of bacterial physiology, including spore formation, plasmid stability, resistance to drugs, biofilm formation, and virulence. The amino acid tryptophan is an indole derivative and the precursor of the neurotransmitter serotonin.
