C7H7Br2

C7H7Br2 refers to a chemical compound with the molecular formula C7H7Br2. This formula indicates that each molecule contains seven carbon atoms, seven hydrogen atoms, and two bromine atoms. The precise arrangement of these atoms determines the specific isomer and its properties. Several structural isomers are possible for this molecular formula, each with distinct chemical and physical characteristics.

Commonly encountered isomers of C7H7Br2 include dibrominated derivatives of toluene (methylbenzene). For instance, 2,4-dibromotoluene (CAS number 615-59-8) is one such compound. In this isomer, the two bromine atoms are attached to the aromatic ring at positions 2 and 4 relative to the methyl group. Other possible isomers could involve bromine substitution at different positions on the toluene ring or even the attachment of bromine atoms to the methyl group.

The synthesis of C7H7Br2 compounds typically involves electrophilic aromatic substitution reactions, where bromine is introduced onto an aromatic precursor. The reaction conditions, such as the catalyst and temperature, can influence the regioselectivity, dictating which isomer is predominantly formed. These compounds may find applications as intermediates in organic synthesis, particularly in the production of pharmaceuticals, agrochemicals, or specialty materials, where the presence of bromine atoms can be leveraged for further chemical transformations. However, specific applications are highly dependent on the individual isomer.
