| Hazard Information | Back Directory | [General Description]
Pale yellow crystals or light tan powder. | [Reactivity Profile]
May be sensitive to light and elevated temperatures on long-term storage. 4-HYDROXY-3-NITROPHENYL ARSONIC ACID(121-19-7) puffs up and deflagrates on heating. Incompatible with strong oxidizers and strong acids. Forms mono-, di-, and trisodium salts. | [Air & Water Reactions]
Insoluble in water. | [Hazard]
Toxic by ingestion, highly toxic. | [Fire Hazard]
Flash point data are not available for this chemical; however, 4-HYDROXY-3-NITROPHENYL ARSONIC ACID is probably combustible. | [Chemical Properties]
BEIGE-BROWN FINE CRYSTALLINE POWDER | [Uses]
4-Hydroxy-3-nitrophenylarsonic Acid is used as a feed additive for chicken to aid in the prevention of coccidiosis caused by E[imeria] tenella and E. necatrix. | [Uses]
antiinfective, preservative | [Uses]
