Oxamide

Oxamide (CAS 471-46-5, EC 207-442-5), also known as oxalamide or ethanediamide, is a diamide derivative of oxalic acid with the molecular formula C2H4N2O2. It carries no E-code designation and is catalogued under NSC 2770 in chemical reference databases.

In agriculture, oxamide functions as a slow-release nitrogen fertiliser: its low water solubility limits leaching, delivering nitrogen progressively as soil microbes hydrolyse the amide bonds. In pulp and paper processing, it acts as a pH buffer, neutralising acidic intermediates during bleaching and refining stages to stabilise process chemistry.

Oxamide is supplied as a fine crystalline powder and is registered under REACH (EC 207-442-5). It falls under HS code 29241900 for customs classification across EU member states. Procurement teams should confirm grade specifications and available pack sizes directly with the supplier to match application requirements.
