Application

2-Dimethylaminoethanol (Deanol) can be used to functionalize the sensitizers in dye-sensitized solar cells to prevent aggregation and to increase the dye adsorption density. It is used in the synthesis of NNO-tridentate Schiff base ligands to prepare zinc alkoxide complexes that catalyze ring-opening polymerization of L-lactide. It is also used in the preparation of ionic liquids.

Numerous drugs are carboxylic acid derivatives containing amino group, and hydrolysis reaction of these agents often generates toxic amines. Thus, the detection of amine impurity is of great importance in drug quality control of these amino group-containing ester and amide.
