N-Ethylmorpholine is widely used as a catalyst in the production of polyurethane foams, where it helps control the reaction between isocyanates and polyols, ensuring proper foam formation and stability. It is also employed as a solvent and intermediate in organic synthesis, particularly in the manufacture of pharmaceuticals, dyes, and agrochemicals. In the textile industry, it acts as a pH regulator and neutralizing agent during dyeing processes. Additionally, it serves as a corrosion inhibitor in metalworking fluids, protecting machinery and extending its lifespan. Its versatility makes it valuable in various industrial applications.
