Oxamide is primarily used as a nitrogen-rich fertilizer in agriculture due to its slow-release properties, which provide a steady supply of nutrients to plants over time. It is also employed as a stabilizer in the production of nitrocellulose-based propellants, where it helps control the combustion rate and enhance safety. In the plastics industry, oxamide serves as a flame retardant, reducing the flammability of materials. Additionally, it is utilized in the synthesis of various organic compounds, including pharmaceuticals and agrochemicals, due to its ability to act as a building block in chemical reactions. Its non-toxic nature makes it suitable for applications in environmentally sensitive areas.
