Arsenic chloride (AsCl3)

Description:
Arsenic chloride (AsCl3) is an inorganic compound characterized by its molecular formula consisting of one arsenic atom and three chlorine atoms. It appears as a colorless to yellowish liquid or solid, depending on temperature and pressure conditions. AsCl3 is known for its pungent, acrid odor and is highly soluble in organic solvents, as well as in water, where it can hydrolyze to form arsenic acid. This compound is classified as a toxic and hazardous material, posing significant health risks upon exposure, including respiratory irritation and potential carcinogenic effects. Arsenic chloride is primarily used in organic synthesis, particularly in the preparation of organoarsenic compounds, and as a reagent in various chemical reactions. It can also act as a Lewis acid, facilitating reactions with nucleophiles. Due to its toxicity and environmental concerns, handling arsenic chloride requires strict safety protocols, including the use of personal protective equipment and proper ventilation.
