diphenylchlorarsine

Diphenylchlorarsine is an organoarsenic compound with the chemical formula (C6H5)2AsCl. It is a colorless, oily liquid that is insoluble in water but soluble in organic solvents. Diphenylchlorarsine is a derivative of arsenic, where two phenyl groups and one chlorine atom are attached to the arsenic atom.

This compound is known for its use as a lachrymatory agent, meaning it irritates the eyes and causes tearing. It was developed and used as a chemical weapon during World War I. Due to its toxicity and irritant properties, its production and use are strictly controlled under international chemical weapons conventions.

Diphenylchlorarsine reacts with water to produce diphenylarsinic acid and hydrochloric acid. It can also react with bases and oxidizing agents. Its handling requires significant precautions due to its hazardous nature. Exposure can cause severe eye irritation, respiratory problems, and skin burns. In industrial settings, its production and handling are subject to stringent safety protocols to prevent accidental release and exposure.
