4-methyl-5-(β-hydroxyethyl)thiazole phosphate, also known as EPN, is an organophosphorus compound that serves as an insecticide and acaricide. It is a colorless, oily liquid with a molecular formula of C6H12NO3PS. EPN is synthesized by reacting 4-methyl-5-(β-chloroethyl)thiazole with phosphorus trichloride. This chemical is effective against a wide range of pests, including aphids, mites, and beetles, and is used in agriculture to protect crops from damage. However, due to its high toxicity and potential environmental and health risks, its use has been restricted or banned in many countries. It is important to handle EPN with caution and follow proper safety measures to minimize exposure and contamination.
The CAS Registry Mumber 3269-79-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,6 and 9 respectively; the second part has 2 digits, 7 and 9 respectively. Calculate Digit Verification of CAS Registry Number 3269-79: (6*3)+(5*2)+(4*6)+(3*9)+(2*7)+(1*9)=102 102 % 10 = 2 So 3269-79-2 is a valid CAS Registry Number.
