Diethyl methyl phosphorotetrathioate, also known as DEPMPT, is an organophosphorus compound with the chemical formula C5H13O4PS4. It is a colorless liquid with a pungent odor and is used as a pesticide and an intermediate in the synthesis of other organophosphorus compounds. DEPMPT is known for its insecticidal properties, particularly against aphids, and is effective due to its ability to inhibit acetylcholinesterase, an enzyme crucial for the proper functioning of the nervous system in insects. It is also used in the production of other pesticides, such as demeton and its derivatives. Due to its toxicity, DEPMPT requires careful handling and is subject to strict regulations to minimize environmental and health risks.
