CAS 1634-78-2: Malaoxon

Description: Malaoxon is an organophosphate compound, specifically a metabolite of the pesticide malathion. It is characterized by its high toxicity, primarily as an acetylcholinesterase inhibitor, which disrupts the normal functioning of the nervous system by preventing the breakdown of the neurotransmitter acetylcholine. This leads to an accumulation of acetylcholine at synapses, resulting in overstimulation of muscles and glands. Malaoxon is a colorless to pale yellow liquid with a faint odor, and it is soluble in organic solvents but has limited solubility in water. Due to its toxicological profile, malaoxon poses significant risks to human health and the environment, necessitating careful handling and regulation. It is important to note that exposure can occur through inhalation, ingestion, or dermal contact, leading to symptoms such as headaches, dizziness, and respiratory distress. As a result, malaoxon is classified as a hazardous substance, and safety precautions are essential when working with or around it.
