Oxamide

Oxamide is the diamide of oxalic acid, with the chemical formula (CONH2)2. It is a white crystalline solid that is poorly soluble in water and ethanol. Oxamide can be synthesized by heating ammonium oxalate or by reacting diethyl oxalate with ammonia. It is an important intermediate in the production of certain polymers and pharmaceuticals.

One of the main uses of oxamide is as a component in slow-release fertilizers. Its low solubility allows for a gradual release of nitrogen into the soil, providing a sustained nutrient supply for plants and reducing nitrogen loss through leaching. This property makes it particularly useful in agricultural applications where long-term nutrient availability is desired.

Oxamide also finds application in the synthesis of various organic compounds. It can be used as a precursor for the production of heterocyclic compounds and has been investigated for its potential in the creation of novel materials. In some instances, it has been explored as a flame retardant due to its nitrogen content. Its stability and relatively low toxicity contribute to its utility in these diverse fields.
