Methyl astatide is an organoastatine chemical compound with the formula CH₃At. ^{[1] [2]} In terms of chemical structure, it is related to methane by replacement of one hydrogen atom by an atom of astatine, the rarest halogen element.

Occurrence

It has been detected as a chemical species but is difficult to study due to the radioactivity of astatine isotopes and small amounts of the compound. ^[3] Due to the rarity and radioactivity of astatine, methyl astatide is a highly specialized compound primarily of interest in nuclear chemistry and advanced research contexts.

Synthesis

Research papers suggest methods for incorporating astatine into organic compounds, similar to radioiodination, including the reaction of astatine with certain organic precursors. ^{[4] [5]}
