[Chemical Properties]

p-Arsanilic acid is an off-white powder. It is slightly soluble in cold water. It is incompatible with oxidizing agents; on hazardous decomposition, p-arsanilic acid produces nitrogen oxides, carbon monoxide, carbon dioxide, nitrogen gas, and oxides of arsenic.
[Health Hazard]

Occupational workers exposed to p-arsanilic acid develop poisoning. The symptoms include, but are not limited to, eye and skin irritation, chemical conjunctivitis and corneal damage, hyperpigmentation of the skin and, perkeratoses of plantar and palmar surfaces, primary irritation and sensitization, digestive tract irritation, gastrointestinal hypermotility, diarrhea, hepatitis, hepatocellular necrosis, central nervous system depression, cardiac disturbances, and liver and kidney damage. The target organs include the kidneys, central nervous system, liver, and cardiovascular system. After a prolonged period of exposure to arsenic compounds, including arsenical dust, workers are known to develop shortness of breath, nausea, chest pains, garlic odor, and impairment of peripheral circulation. The toxicological properties of p-arsanilic acid have not been fully investigated.

[storage]

p-Arsanilic acid should be kept stored in a tightly closed container in a cool, dry, wellventilated area. It should be kept away from incompatible materials, dust generation, excess heat, and strong oxidants.
[Precautions]

Occupational workers should wash thoroughly after using p-arsanilic acid. Any contaminated clothing should be washed before reuse. Work areas should have adequate ventilation and minimum dust generation and accumulation. Workers should avoid any kind of contact of p-arsanilic acid with the eyes, skin, clothing, ingestion or inhalation.
[Safety Profile]

Poison by intravenous and intraperitoneal routes. Moderately toxic by ingestion. Flammable, decomposes with heat to yield flammable vapors. When heated to decomposition or on contact with acid or acid fumes it emits highly toxic fumes of As and NO,. See also ARSENIC COMPOUNDS and ANILINE.
