Description

General description

Solution of 4-(dimethylamino)benzaldehyde and hydrochloric acid in n-butanol.

Application

In the presence of oxygen, some bacteria, like E. coli, are able to split tryptophan into indole and α-aminopropionic acid. This reagent is for detecting the indole and identifying the indole-positive and indole-negative microorganisms.
