methylarsonous

Methylarsonous is an organoarsenic compound with the chemical formula CH3AsO. It is a derivative of arsenic acid where one hydroxyl group has been replaced by a methyl group. This compound is a colorless liquid and is considered an intermediate in the metabolism of certain organic arsenicals, particularly those used as herbicides. Methylarsonous is known to be toxic, as are many arsenic compounds. Its toxicity stems from the arsenic atom's ability to interfere with biological processes. It can be formed through the reduction of methylarsonic acid (CH3AsO(OH)2) or through the methylation of inorganic arsenic. In the environment, methylarsonous can be produced by microorganisms, particularly in anaerobic conditions, as part of the natural biogeochemical cycle of arsenic. Exposure to methylarsonous can occur through contaminated water or food. Due to its toxicity and potential environmental persistence, its presence and behavior are subjects of scientific study and regulatory concern.
