Monomethylarsonous acid (MMA) is an organoarsenic compound characterized by its chemical structure, which includes a methyl group attached to an arsenic atom. It is a colorless to pale yellow liquid that is soluble in water and exhibits a weak acidic nature. MMA is known for its toxicity and potential health risks, particularly as it can interfere with cellular processes and is considered a carcinogen. The compound is often studied in the context of environmental chemistry, particularly regarding its presence in contaminated water sources and its effects on human health and ecosystems. Its behavior in biological systems is of significant interest, as it can undergo various metabolic transformations. Additionally, MMA is used in research to understand arsenic metabolism and its implications in toxicology. Proper handling and disposal are crucial due to its hazardous nature, and safety protocols should be followed when working with this substance.
