Indole (CAS NO 120-72-9)
Description:
Indole, also called Benzopyrrole, an aromatic heterocyclic organic compound occurring in some flower oils, such as jasmine and orange blossom, in coal tar, and in fecal matter. It has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered nitrogen-containing pyrrole ring. It can be produced by bacteria as a degradation product of the amino acid tryptophan. It occurs naturally in human feces and has an intense fecal smell. This off flavour occurs in beer due to contaminant coliform bacteria during the primary fermentation stage of beer brewing. At very low concentrations, however, it has a flowery smell, and is a constituent of many flower scents (such as orange blossoms) and perfumes. Natural jasmine oil, used in the perfume industry, contains around 2.5% of indole. Indole also occurs in coal tar. The participation of the nitrogen lone electron pair in the aromatic ring means that indole is not a base, and it does not behave like a simple amine.
Application:
Indole can be widely used in jasmine, lilac, orange blossom, gardenia, honeysuckle, lotus, narcissus, ylang-ylang, grassland, white orchid and other floral flavor. It is also commonly used together with methyl hydrazine for the preparation of artificial civet cats, which can be used in chocolate, raspberry, strawberry, bitter orange, coffee, nuts, cheese, grapes and fruity notes.
