Chemische Eigenschaften
off-white fine crystalline powder
Verwenden
4-Aminophenylarsonic acid is an organoarsenic compound. 4-Aminophenylarsonic acid is a highly toxic contaminant and can be found in plants growing in contaminated soil. 4-Aminophenylarsonic acid was used as an additive in animal feed. It has also been used in treating dysentery in swine as well as having potential chemotherapeutic activity.
Hazard
Toxic.
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.
Sicherheitsprofil
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.
Lager
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.
l?uterung methode
Crystallise it from water or ethanol/ether. POISONOUS. [Beilstein 16 I 466.]
Vorsichtsma?nahmen
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.
