It is a derivative of phenol, featuring a fluorine atom at the 3-position and an azo group (-N=N-) connecting a 3-nitrophenyl group to the 4-position of the phenol ring. Phenol, 3-fluoro-4-[(3-nitrophenyl)azo]- is characterized by its yellow crystalline appearance and is soluble in organic solvents such as ethanol and acetone. It is primarily used as a chemical intermediate in the synthesis of dyes and pigments, particularly those with yellow hues. Due to its azo structure, it can form various colored compounds when combined with different metal ions, making it valuable in the production of colorants for various applications.
The CAS Registry Mumber 404-67-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,0 and 4 respectively; the second part has 2 digits, 6 and 7 respectively. Calculate Digit Verification of CAS Registry Number 404-67: (5*4)+(4*0)+(3*4)+(2*6)+(1*7)=51 51 % 10 = 1 So 404-67-1 is a valid CAS Registry Number.
