The diamide of oxalic acid: Oxamide is the diamide of oxalic acid, with the compact formula (CONH2)2. It is a stable white solid used as a chemical intermediate and reference material, and it has attracted particular interest as a slow-release nitrogen source. Its stability and low water solubility are exactly the properties that make it useful where a controlled, gradual release of nitrogen or a dependable solid reference compound is wanted.
Uses across chemistry and agriculture: As an intermediate, oxamide participates in various syntheses, and as a reference material it provides a well-defined compound for characterization and method work. Its best-known applied interest is as a slow-release fertilizer component: because it releases nitrogen gradually rather than all at once, it has been studied as a way to deliver nutrient nitrogen steadily over time, reducing losses compared with more soluble nitrogen sources.
Verified identity and purity: This TCI product (catalog O0086) is a minimum 98.0% grade, CAS number 471-46-5, with molecular formula (CONH2)2 and molecular weight 88.07. It is a white to almost white powder to crystal. Confirming these identifiers ensures the correct compound and grade are received, supporting consistent behavior whether the material is used as an intermediate, a reference, or a subject of applied research.
Handling and storage: As with any laboratory reagent, the Safety Data Sheet should be reviewed before handling, and suitability confirmed for the specific application. Stored as a stable solid, kept properly closed and according to the manufacturer's guidance, oxamide retains its purity over its shelf life, providing a reliable, easy-to-handle material for synthesis, reference, and specialty applications.
