CAS 2496-92-6: O,O-diethyl S-[2-(ethylsulfinyl)ethyl] phosphorothioate
Description:O,O-Diethyl S-[2-(ethylsulfinyl)ethyl] phosphorothioate, with the CAS number 2496-92-6, is an organophosphorus compound primarily recognized for its use as an insecticide and acaricide. This chemical features a phosphorothioate structure, which includes a phosphorus atom bonded to sulfur and oxygen, contributing to its biological activity. It is characterized by the presence of ethyl groups and a sulfinyl moiety, which enhance its efficacy in pest control. The compound typically exhibits moderate to high toxicity to non-target organisms, including humans, necessitating careful handling and application. Its mode of action involves the inhibition of acetylcholinesterase, leading to the accumulation of acetylcholine in synapses, which disrupts normal nerve function. O,O-Diethyl S-[2-(ethylsulfinyl)ethyl] phosphorothioate is generally soluble in organic solvents and has limited solubility in water, influencing its environmental behavior and persistence. As with many organophosphates, it is subject to regulatory scrutiny due to potential health and environmental risks associated with its use.
