25476-46-4 Usage
General Description
Phosphorothioic acid O-[2-(ethylsulfinyl)ethyl]O,O-dimethyl ester, also known as ethion, is an organophosphate insecticide and acaricide used to control a wide range of pests in agriculture, horticulture, and forestry. It works by inhibiting the enzyme acetylcholinesterase in the nervous systems of insects and mites, ultimately leading to paralysis and death. Ethion is highly toxic to aquatic organisms and can persist in the environment for a long time, posing a risk to non-target species and ecosystems. Due to its potential to cause harm to humans and the environment, the use of ethion has been restricted or banned in many countries, and there is a growing effort to find safer and more sustainable alternatives for pest control in agriculture.
Check Digit Verification of cas no
The CAS Registry Mumber 25476-46-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,4,7 and 6 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 25476-46:
(7*2)+(6*5)+(5*4)+(4*7)+(3*6)+(2*4)+(1*6)=124
124 % 10 = 4
So 25476-46-4 is a valid CAS Registry Number.

Selective Sulfur Oxygenation in Phosphoroamidate, Thionophosphate, and Thiophosphate Agrochemicals by Perfluoro-cis-2,3-dialkyloxaziridine
Terreni, Marco,Pregnolato, Massimo,Resnati, Giuseppe,Benfenati, Emilio
, p. 7981 - 7992 (2007/10/02)
Several organophsophorus agrochemicals 2a-g with thioether, phosphoramidic, phosphorothioic, and phosphorothionic functions were reacted with perfluoro-cis-2-n-butyl-3-n-propyloxaziridine 1.The selective oxygenation of sulfide function to give sulfoxide derivatives 3a-g occured in high yields without overoxidation to sulfone products.Sulfoxides 3a-e were further oxidized under mild conditions to the corresponding sulfones 4a-e.All the products are themselves of interest as analytical environmental standards and their preparation is described in detail.
