Ethyl-phosphonic acid diethylamide fluoride, also known as EPN, is a chemical compound with the molecular formula C6H16FNO3P. It is an organophosphorus compound that belongs to the class of phosphonic acids and their derivatives. EPN is primarily used as an insecticide and acaricide, targeting a wide range of pests, including aphids, mites, and other agricultural pests. It works by inhibiting the activity of acetylcholinesterase, an enzyme essential for the proper functioning of the nervous system in insects. This inhibition leads to the accumulation of acetylcholine, causing overstimulation and ultimately paralysis and death of the target pests. EPN is known for its effectiveness and low mammalian toxicity, making it a popular choice in agricultural applications. However, it is important to handle and apply this chemical responsibly, following safety guidelines to minimize potential risks to human health and the environment.
The CAS Registry Mumber 667-02-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,6 and 7 respectively; the second part has 2 digits, 0 and 2 respectively. Calculate Digit Verification of CAS Registry Number 667-02: (5*6)+(4*6)+(3*7)+(2*0)+(1*2)=77 77 % 10 = 7 So 667-02-7 is a valid CAS Registry Number.
