2,4,6-Tribromoaniline, also known as sym-tribromoaniline, is a brominated aromatic amine characterized by the substitution of three bromine atoms at the 2, 4, and 6 positions of the aniline ring. 2,4,6-tribromoaniline is typically a white to pale yellow crystalline solid with applications in organic synthesis, particularly as an intermediate in the production of dyes, pharmaceuticals, and flame retardants. Its brominated structure imparts high reactivity in electrophilic substitution reactions, while the amino group allows for further functionalization. Due to its potential toxicity and environmental persistence, handling requires appropriate safety precautions.
The CAS Registry Mumber 71018-40-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,0,1 and 8 respectively; the second part has 2 digits, 4 and 0 respectively. Calculate Digit Verification of CAS Registry Number 71018-40: (7*7)+(6*1)+(5*0)+(4*1)+(3*8)+(2*4)+(1*0)=91 91 % 10 = 1 So 71018-40-1 is a valid CAS Registry Number.
