Roxarsone Usage And Synthesis

Chemical Properties

BEIGE-BROWN FINE CRYSTALLINE POWDER

Uses

antiinfective, preservative

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

Formerly in manufacture of arsphenamines; as reagent for zirconium.

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.]
