Other closely related compounds include trimethylarsine, which is also toxic, and arsine, a colorless, flammable gas. Cacodyl was once used in organic chemistry as a reagent and as a poison, but its use has since been largely discontinued due to its extreme toxicity and hazardous nature. Today, it is most often studied as a curiosity, and to gain insight into the workings of organic chemistry and organometallic compounds.
