CAS 121-75-5: Malathion

Description: Malathion is an organophosphate insecticide widely used in agriculture and public health for pest control. It is characterized by its relatively low toxicity to mammals compared to other organophosphates, making it a preferred choice for various applications. Malathion is a colorless to pale yellow liquid with a slightly sweet odor and is soluble in organic solvents but has limited solubility in water. Its chemical structure includes a phosphate group, which is responsible for its insecticidal properties by inhibiting the enzyme acetylcholinesterase, leading to the accumulation of acetylcholine and resulting in the disruption of normal nerve function in pests. Malathion is often applied in formulations that include emulsifiable concentrates or granules, and its effectiveness can be influenced by environmental factors such as temperature and humidity. While it is generally considered safe when used according to guidelines, concerns about its potential environmental impact and effects on non-target organisms have led to ongoing research and regulatory scrutiny. Proper handling and application practices are essential to minimize risks associated with its use.
