CH3AsH2

CH3AsH2, also known as methylarsine, is an organoarsenic compound with the chemical formula CH3AsH2. It is the simplest organic derivative of arsine (AsH3). Methylarsine is a colorless gas at room temperature and pressure. Its structure consists of a methyl group (CH3) bonded to an arsenic atom, which is also bonded to two hydrogen atoms.

This compound is a member of the family of primary arsines, meaning the arsenic atom is bonded to one alkyl group and two hydrogen atoms. Like other arsines, methylarsine is expected to be highly toxic and possess a strong, unpleasant odor. Its reactivity is influenced by the presence of the arsenic-hydrogen bonds, which can undergo various chemical transformations, including oxidation and substitution reactions.

Methylarsine is not a widely studied compound and is primarily of academic interest. It may be synthesized through specific organometallic reactions, but it is not a commercially significant chemical. Due to its potential toxicity and the hazardous nature of related arsenic compounds, handling and experimentation with methylarsine require extreme caution and specialized laboratory equipment. Its environmental impact and long-term effects are not extensively documented.
