4-Dimethylaminobenzaldehyde is used to prepare colorful Schiff base adducts with amines, pyrroles and indoles. It is often used in the Ehrlich reaction, test for the presence of indoles in a sample containing alkaloids and determination of hydrazine.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
