N-(4-Fluorophenyl)-N-nitroso-benzamid, also known as 4-fluoro-N-(4-nitrosophenyl)benzamide, is an organic compound with the chemical formula C13H9FN2O2. It is a derivative of benzamide, featuring a nitroso group (-N=O) and a fluorine atom attached to the phenyl ring. N-<4-Fluor-phenyl>-N-nitroso-benzamid is often used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals due to its unique reactivity and structural properties. The presence of the nitroso group makes it a potential precursor for the formation of diazonium salts, which are important in the synthesis of dyes and other organic compounds. Additionally, the fluorine atom can influence the electronic properties and metabolic stability of the molecules in which it is incorporated, making it a valuable building block in the development of new drugs and chemical compounds.
The CAS Registry Mumber 728-11-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,2 and 8 respectively; the second part has 2 digits, 1 and 1 respectively. Calculate Digit Verification of CAS Registry Number 728-11: (5*7)+(4*2)+(3*8)+(2*1)+(1*1)=70 70 % 10 = 0 So 728-11-0 is a valid CAS Registry Number.
