C2H53As

C2H53As, also known as triethylarsine, is an organoarsenic compound with the chemical formula (C2H5)3As. It is a colorless liquid with a strong, unpleasant odor. Triethylarsine is primarily used as a precursor in the synthesis of other arsenic compounds and as a ligand in organometallic chemistry. It is also used in the production of certain pesticides and as a dopant in semiconductor materials.

The compound is highly toxic and can cause severe health issues upon exposure. Inhalation of triethylarsine can lead to respiratory problems, while ingestion can result in gastrointestinal distress. Prolonged exposure can cause arsenic poisoning, which can be fatal. Due to its toxicity, handling of triethylarsine requires strict safety measures, including the use of personal protective equipment and proper ventilation.

Triethylarsine is typically prepared by the reaction of arsenic trichloride with ethanol in the presence of a base. The reaction produces triethylarsine and hydrogen chloride as byproducts. The compound can be stored under refrigeration to prevent decomposition.

In summary, C2H53As, or triethylarsine, is a toxic organoarsenic compound used in various chemical syntheses and industrial applications. Its handling requires careful consideration of safety protocols due to its hazardous nature.
