About Quinaldine Red

Quinaldine Red is synthesized by a condensation reaction between the methyl group of 1-ethyl-2-methylquinolinium iodide and the carbonyl of para-dimethylaminobenzaldehyde. Quinaldine red is a dark green solid that does not dissolve easily in water. It is used as colored indicator and is also used as a fluorescence probe and an agent in bleaching.

Quinaldine red is also used as an indicator in experiments. When being used as an indicator, a color change is involved in order to indicate a change in the pH.
