N,N-Diethylhydroxylamine is widely used as an oxygen scavenger in water treatment processes, particularly in boiler systems, to prevent corrosion by removing dissolved oxygen. It is also employed in the polymer industry as a stabilizer and inhibitor to prevent unwanted polymerization during the production and storage of monomers like styrene and acrylates. Additionally, it serves as a reducing agent in various chemical reactions, including the synthesis of pharmaceuticals and agrochemicals. Its ability to act as a radical scavenger makes it valuable in controlling oxidation processes in industrial applications, ensuring the stability and longevity of products.
