| Common Name | Adrenochrome |
|---|
| Description | Adrenochrome (CAS: 54-06-8) belongs to the class of organic compounds known as indoles and derivatives. These are organic compounds containing an indole, which is a bicyclic ring system made up of a six-membered benzene ring fused to a five-membered nitrogen-containing pyrrole ring. Adrenochrome is a red-coloured oxidation product of adrenaline (epinephrine) that was first isolated and identified by Green and Richter in 1937 (PMID: 16746378 ). It is highly soluble in water. Adrenochrome can be synthesized from adrenalin via oxidation with silver oxide (PMID: 4581204 ). |
