Useful:

• Chemical Classes: Metals -> Arsenic Compounds, Inorganic
• Canonical SMILES: Cl[As](Cl)Cl
• Inhalation Risk: A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20 °C.
• Effects of Short Term Exposure: The substance is severely irritating to the eyes, skin and respiratory tract. The substance may cause effects on the gastrointestinal tract, cardiovascular system and central nervous system. This may result in severe gastroenteritis, loss of fluids and electrolytes, cardiac disorders, shock and convulsions. Exposure above the OEL could cause death. The effects may be delayed. Medical observation is indicated.
• Effects of Long Term Exposure: Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the mucous membranes, skin, peripheral nervous system, liver and bone marrow. This may result in pigmentation disorders, hyperkeratosis, perforation of the nasal septum, neuropathy, liver impairment and anaemia. This substance is carcinogenic to humans. Animal tests show that this substance possibly causes malformations in human babies.
• Physical properties: Colorless oily liquid; fumes in air; density 2.163 g/ml at 20°C; refractive index 1.621 at 14°C; melts at 0.16°C; boils at 130.2°C; vapor pressure 9.75 torr at 25°C; decomposes in water; soluble in alcohol, ether, HCl and HBr.
• Uses: Arsenic trichloride (AsCl3), also known as arsenic chloride, is used in the pharmaceutical industry and to make insecticides and ceramics. Arsenic Trichloride is an highly toxic inorganic compounds and is an intermediate in the manufacture of organoarsenic compounds. In the ceramic industry; in syntheses of chlorine-contg arsenicals, e.g., chloro derivatives of arsine.
