Ethanamine is widely used in organic synthesis, particularly as an intermediate in the production of pharmaceuticals, agrochemicals, and dyes. It serves as a building block for the preparation of various nitrogen-containing compounds, including surfactants and corrosion inhibitors. In the pharmaceutical industry, it is involved in the synthesis of certain local anesthetics and antihistamines. It also finds use in the manufacture of quaternary ammonium compounds, which are employed as disinfectants and fabric softeners. Additionally, ethanamine acts as a solvent and catalyst in some industrial reactions due to its basic nature.
