CH3COOO
CH3COOO is the condensed formula often used for the peroxyacetyl radical CH3COOO•, an important reactive intermediate in combustion and atmospheric chemistry. In written form without the radical dot, CH3COOO can be seen as the neutral fragment, but in most chemical contexts the species is a radical and highly reactive.
The radical has a peroxyacyl structure, with an acetyl group (CH3CO–) bound to a peroxide moiety (–OO•).
Formation of CH3COOO• occurs in situ from smaller radicals. A common route is the reaction of an
In atmospheric chemistry, CH3COOO• plays a central role in the formation of secondary pollutants. It readily
Because CH3COOO• is a transient radical, it is typically studied and referenced in mechanistic schemes and
