| Definition | ChEBI: An organoarsonic acid where the organyl group is 4-hydroxy-3-nitrophenyl. |
| General Description | Pale yellow crystals or light tan powder. |
| Air & Water Reactions | Insoluble in water. |
| Reactivity Profile | May be sensitive to light and elevated temperatures on long-term storage. Roxarsone puffs up and deflagrates on heating. Incompatible with strong oxidizers and strong acids. Forms mono-, di-, and trisodium salts. |
| Hazard | Toxic by ingestion, highly toxic. |
| Fire Hazard | Flash point data are not available for Roxarsone ; however, Roxarsone is probably combustible. |
| Purification Methods | It crystallises from water and is used for the spectroscopic detection of Zn. [Beilstein 16 II 468, 16 III 1073, 16 IV 1188.] |
