1,2,3,4,5-Pentabromo-6-methoxybenzene is an organic compound with the chemical formula C7H3Br5O. It is a brominated derivative of methoxybenzene, featuring five bromine atoms attached to the benzene ring and a methoxy group at the sixth position. 1,2,3,4,5-pentabromo-6-methoxybenzene is known for its high reactivity and stability, making it a valuable intermediate in the synthesis of various pharmaceuticals, agrochemicals, and flame retardants. Due to its unique structure, it exhibits properties such as high electron affinity and lipophilicity, which are crucial in its applications. However, it is essential to handle 1,2,3,4,5-pentabromo-6-methoxybenzene with care, as it may pose potential health and environmental risks due to its bromine content.

Check Digit Verification of cas no

The CAS Registry Mumber 1825-26-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,2 and 5 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1825-26:
(6*1)+(5*8)+(4*2)+(3*5)+(2*2)+(1*6)=79
79 % 10 = 9
So 1825-26-9 is a valid CAS Registry Number.

The rates were measured and the orientation was studied for the methoxydebromination of all polybromobenzenes C6HnBr6-n (n = 0-3) in pyridine at 115 deg C.From comparison of the partial rates of substitution of the bromine atom at various positions of the benzene ring it was found that the activating effect of the bromine atom in relation to the point of nucleophilic attack changes in the order o-Br > m-Br > p-Br, and the directing selectivity of the bromine is low (compared with fluorine in the methoxydefluorination of polyfluorobenzenes) and increases with decrease in the number of bromine atoms in the aromatic ring of the substrate.
