Isopropyl-thiophosphoramidic acid diethyl ester, also known as isopropyl phosphoramidate or isopropyl-PAM, is an organophosphorus compound with the chemical formula C7H18NO3PS. It is a colorless, oily liquid that is soluble in organic solvents. isopropyl-thiophosphoramidic acid diethyl ester is primarily used as an intermediate in the synthesis of various pesticides, particularly in the production of isopropyl phosphorothioate, which is a widely used insecticide. It is also employed as a precursor in the preparation of other organophosphorus compounds. Due to its potential toxicity and its role in the formation of harmful pesticides, handling and disposal of isopropyl-thiophosphoramidic acid diethyl ester must be done with caution, adhering to strict safety protocols to minimize environmental and health risks.
The CAS Registry Mumber 6737-25-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,3 and 7 respectively; the second part has 2 digits, 2 and 5 respectively. Calculate Digit Verification of CAS Registry Number 6737-25: (6*6)+(5*7)+(4*3)+(3*7)+(2*2)+(1*5)=113 113 % 10 = 3 So 6737-25-3 is a valid CAS Registry Number.
