Trimethylarsine (data page)

Trimethylarsine, with the molecular formula (CH₃)₃As, is a volatile organoarsenic compound. It is a colorless liquid at room temperature with a characteristic garlic-like odor. It is commonly abbreviated as Me₃As.

Trimethylarsine is a highly toxic compound. It is produced by some microorganisms through the biomethylation of arsenic compounds, playing a role in the arsenic cycle in the environment. Specifically, microorganisms can transform inorganic arsenic into methylated forms, including trimethylarsine, which is then released into the atmosphere. This process contributes to the volatilization and dispersal of arsenic.

It is used in research settings and is of interest in environmental studies due to its role in arsenic biogeochemistry. Due to its toxicity and volatility, trimethylarsine requires careful handling and storage procedures. It is typically synthesized and handled under inert atmospheric conditions to prevent oxidation or decomposition. The synthesis often involves the reaction of an arsenic halide precursor with a methylating agent.
