Oxanilide TCI O0087

Oxanilide from TCI is N,N'-diphenyloxamide, the diamide formed from oxalic acid and aniline. Its molecule has a central oxamide core with a phenyl ring on each side. This solid compound is used as a building block and as a model compound in organic chemistry and materials science laboratories. Oxanilide and its derivatives are well known in research on UV stabilizers and polymer additives. The material also serves as a ligand in coordination chemistry and as a starting material for synthesizing anilide derivatives and certain heterocyclic compounds.

Researchers choose this material for its rigid, planar structure, which carries two amide groups that form strong intermolecular hydrogen bonds. Because of this, oxanilide tends to be thermally stable, is poorly soluble in many common solvents, and readily forms well-ordered crystals. The N–H and C=O groups on the oxamide core can bind metal ions through several coordination modes, which makes the compound useful in metal complex research. The oxanilide framework is also the structural basis of many commercial UV absorbers, so it is relevant to photostability studies as a reference or model structure.

In Indonesia, oxanilide is useful to research laboratories working on polymers, plastics, and coatings that study how materials hold up under strong tropical sunlight. University organic chemistry and inorganic chemistry groups can use it for coordination chemistry experiments, crystal packing and hydrogen-bonding studies, and synthesis projects that need an anilide-based starting material. Materials science and industrial R&D laboratories can also use it as a model compound when they develop and evaluate additive formulations for local climate conditions.

• UV stabilizer research: the oxanilide framework is the structural basis of many commercial UV absorbers, so the compound is a sensible model for photostability and degradation studies.
• Polymer additive development: oxanilide and its derivatives are studied as polymer additives, so researchers can use it to explore how additives protect plastics and coatings from light exposure.
• Coordination chemistry: the N–H and C=O groups on the oxamide core can bind metal ions through several coordination modes, which supports the synthesis and study of new metal complexes.
• Organic synthesis: as a building block, oxanilide is a practical starting material for preparing anilide derivatives and certain heterocyclic compounds in research-scale synthetic work.
• Crystal engineering and solid-state studies: its rigid planar structure and strong intermolecular hydrogen bonding make it a good model compound for studying ordered crystal formation and molecular packing.

Store oxanilide in its original tightly closed container in a cool, dry, well-ventilated area, away from direct sunlight, heat sources, and incompatible materials such as strong oxidizing agents. Glass or chemically resistant plastic containers with secure caps work well once the original packaging is opened. Handle the solid carefully to avoid creating dust, and weigh it in a fume hood or a well-ventilated area. Wear standard laboratory protective equipment, including safety glasses, gloves, and a lab coat. Avoid inhalation, ingestion, and contact with skin or eyes. Always check the TCI Safety Data Sheet for specific hazard information, and dispose of waste according to local regulations.
