Description
Application
In the presence of oxygen some bacteria likeE. coli are able to split tryptophan into indole and -aminopropionic acid. This reagent is for detecting the indole and identifying the indole-positive and indole-negative microorganisms.
Purpose
For R&D use onlynot for drug household or other uses.
General Description
para-Dimethylaminobenzaldehyde is an organic compound containing amine and aldehyde moieties which is used in Ehrlichs reagent and Kovacs reagent to test for indoles. The carbonyl group typically reacts with the electron rich 2-position of the indole but may also react at the C-3 or N-1 positions.
