dimethylarsinoyl

Dimethylarsinoyl is an organoarsenic compound with the chemical formula (CH3)2AsO. It is a derivative of dimethylarsine, where the hydrogen atom bonded to arsenic is replaced by an oxygen atom. This compound is a member of the family of organic arsenic oxides.

Dimethylarsinoyl can be formed through the oxidation of dimethylarsine or other related dimethylarsine compounds. It is a colorless solid and is soluble in water and many organic solvents. The arsenic atom in dimethylarsinoyl is in the +3 oxidation state.

The presence of the dimethylarsinoyl moiety is significant in environmental and biological contexts. Organoarsenic compounds, including those containing the dimethylarsinoyl group, can arise from both natural biological processes and anthropogenic activities. In biological systems, methylation of inorganic arsenic can lead to the formation of various methylated arsenicals, and dimethylarsinoyl-containing species are often intermediates or end products of arsenic metabolism in many organisms.

Due to the toxicity of arsenic compounds, dimethylarsinoyl and related substances are of interest in toxicology and environmental chemistry. Understanding the formation, transformation, and fate of these compounds is important for assessing risks associated with arsenic exposure.
