CAS 56-38-2: Parathion

Description: Parathion, with the CAS number 56-38-2, is an organophosphate insecticide known for its potent neurotoxic effects. It is a colorless to pale yellow liquid with a characteristic odor, often described as similar to that of rotten eggs. Parathion functions by inhibiting the enzyme acetylcholinesterase, leading to an accumulation of acetylcholine in the nervous system, which can result in overstimulation of muscles and glands. This mechanism makes it highly effective as an insecticide but also poses significant risks to human health and the environment. Parathion is classified as highly toxic, and exposure can occur through inhalation, ingestion, or skin contact. Due to its hazardous nature, many countries have restricted or banned its use. In terms of physical properties, Parathion has a relatively low solubility in water but is soluble in organic solvents. Its persistence in the environment raises concerns regarding its potential for bioaccumulation and long-term ecological impact. Proper handling and safety measures are essential when dealing with this chemical.
