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] Formerly in manufacture of arsphenamines; as reagent for zirconium.
[Definition] ChEBI: An organoarsonic acid where the organyl group is 4-hydroxy-3-nitrophenyl.
[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.]
