4-(dibromomethyl)benzoyl bromide is an organic compound with the chemical formula C8H5Br3O. It is a white crystalline solid that is soluble in organic solvents such as dichloromethane and acetone. 4-(dibromomethyl)benzoyl bromide is characterized by the presence of a benzoyl group (C6H5-CO-) attached to a dibromomethyl group (CHBr2) at the 4-position of the benzene ring. The molecule also has a bromine atom attached to the carbonyl carbon of the benzoyl group, making it a brominated derivative. 4-(dibromomethyl)benzoyl bromide is primarily used as an intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds due to its reactive nature and ability to undergo substitution reactions. It is important to handle 4-(dibromomethyl)benzoyl bromide with care, as it is toxic and can cause harm to the environment and human health.

Check Digit Verification of cas no

The CAS Registry Mumber 877-75-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,7 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 877-75:
(5*8)+(4*7)+(3*7)+(2*7)+(1*5)=108
108 % 10 = 8
So 877-75-8 is a valid CAS Registry Number.

Synthesis of 4-(Dibromomethyl)benzaldehyde by Catalytic Debromophosphoryl- and Phosphonyloxylation of 1,4-Bis(dibromomethyl)benzene with Phosphorus(IV) Acid Methyl Esters and Its Properties

Gazizov,Ivanova, S. Yu.,Khairullin,Kirillina, Yu. S.,Gazizova

, p. 2243 - 2250 (2018)

A new procedure has been developed for the simultaneous preparation of terephthalaldehyde and 4-(dibromomethyl)benzaldehyde by catalytic debromophosphoryl- and phosphonyloxylation of 1,4-bis- (dibromomethyl)benzene with P(IV) acid methyl esters. The reaction of 4-(dibromomethyl)benzaldehyde with ortho esters in the presence of sulfuric acid gave the corresponding acetals, whereas in the presence of ZnCl2 terephthalaldehyde bis-acetals were formed. 4-(Dibromomethyl)benzaldehyde and its acetal were converted to methyl 4-(dibromomethyl)- and 4-(dimethoxymethyl)benzoates which were phosphorylated by the action of chlorophosphines, as well as by successive treatment with phosphorus(III) chloride and P(III) esters.
