4-(2-Diethylaminoethoxy-4'-nitrodiphenyl Ether, also known as DEONE, is a chemical compound with the molecular formula C18H22N2O4. It is an ether derivative of diphenylamine, featuring a nitro group at the para position of one phenyl ring and a diethylaminoethoxy group at the para position of the other phenyl ring. DEONE is primarily used as a corrosion inhibitor in various industrial applications, such as oil and gas production, water treatment, and metalworking fluids. It is effective in preventing the formation of rust and other types of corrosion in metal surfaces when exposed to water and other corrosive agents. The compound's chemical structure allows it to form a protective film on metal surfaces, thereby inhibiting the electrochemical reactions that lead to corrosion.
The CAS Registry Mumber 1444-23-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,4 and 4 respectively; the second part has 2 digits, 2 and 3 respectively. Calculate Digit Verification of CAS Registry Number 1444-23: (6*1)+(5*4)+(4*4)+(3*4)+(2*2)+(1*3)=61 61 % 10 = 1 So 1444-23-1 is a valid CAS Registry Number.
