2-fluoro-4-nitroso-phenol is an organic compound characterized by its molecular formula C6H4FNO3. It features a phenol ring with a fluorine atom at the 2nd position, a nitroso group (-NO) at the 4th position, and a hydroxyl group (-OH) attached to the same carbon as the nitroso group. 2-fluoro-4-nitroso-phenol is known for its potential applications in the synthesis of various pharmaceuticals and chemical intermediates. Due to the presence of both electron-withdrawing fluorine and nitroso groups, 2-fluoro-4-nitroso-phenol exhibits unique chemical properties, such as reactivity and stability, which can be exploited in various chemical reactions. However, it is important to handle 2-fluoro-4-nitroso-phenol with care, as it may have potential health and environmental hazards due to its nitroso functional group.
The CAS Registry Mumber 351-49-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,5 and 1 respectively; the second part has 2 digits, 4 and 9 respectively. Calculate Digit Verification of CAS Registry Number 351-49: (5*3)+(4*5)+(3*1)+(2*4)+(1*9)=55 55 % 10 = 5 So 351-49-5 is a valid CAS Registry Number.
