4,4'-Fluorene-9,9-diyl-bis-morpholine, also known as FDBM, is a chemical compound with the molecular formula C21H22N2O2. It is a white crystalline solid that is soluble in water and various organic solvents. FDBM is primarily used as a corrosion inhibitor in the oil and gas industry, as it effectively prevents the formation of rust and other types of corrosion in metal pipelines and storage tanks. The compound works by forming a protective film on the metal surface, which inhibits the reaction between the metal and corrosive agents. Additionally, FDBM has been studied for its potential applications in other industries, such as agriculture and pharmaceuticals, due to its unique chemical properties and ability to form stable complexes with various metal ions.
The CAS Registry Mumber 2089-68-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,8 and 9 respectively; the second part has 2 digits, 6 and 8 respectively. Calculate Digit Verification of CAS Registry Number 2089-68: (6*2)+(5*0)+(4*8)+(3*9)+(2*6)+(1*8)=91 91 % 10 = 1 So 2089-68-1 is a valid CAS Registry Number.
