Trimethylarsine (CAT: R025568) is a volatile, organoarsenic compound characterized by its fishy odor and high reactivity. It is primarily used in research as a chemical intermediate and in studies involving arsenic metabolism, environmental toxicology, and microbial arsenic biotransformation. Certain microorganisms, especially in anaerobic environments, produce trimethylarsine as a part of their arsenic detoxification process, making it relevant in geochemical and ecological investigations. Due to its toxicity and volatility, it must be handled with strict safety precautions. Trimethylarsine is also studied as a model compound for understanding the behavior of volatile arsenicals in biological and atmospheric systems.
