化合物简介
Isoamyl alcohol (also known as isopentyl alcohol) is a clear, colorless alcohol with the formula (CH3)2CHCH2CH2OH. It is one of several isomers of amyl alcohol. It is a main ingredient in the production of banana oil, an ester found in nature and also produced as a flavouring in industry. It is also the main ingredient of Kovac's reagent, used for the bacterial diagnostic indole test.
