C6H4BrSO3H

C6H4BrSO3H is the chemical formula for bromobenzenesulfonic acid. This compound is an organosulfur compound and a derivative of benzene. It consists of a benzene ring substituted with a bromine atom and a sulfonic acid group. The relative positions of these two substituents on the benzene ring can vary, leading to different isomers. Common isomers include ortho-bromobenzenesulfonic acid (where the bromine and sulfonic acid groups are adjacent), meta-bromobenzenesulfonic acid (where they are separated by one carbon atom), and para-bromobenzenesulfonic acid (where they are on opposite sides of the ring).

Bromobenzenesulfonic acids are typically strong acids due to the presence of the sulfonic acid group, which readily donates a proton. They are often encountered as intermediates in organic synthesis. For example, they can be synthesized through the sulfonation of bromobenzene or the bromination of benzenesulfonic acid. These compounds can participate in various chemical reactions, including further electrophilic aromatic substitution, nucleophilic substitution of the bromine atom under certain conditions, and reactions involving the sulfonic acid group. Their physical properties, such as solubility and melting point, will depend on the specific isomer. They are generally soluble in water and polar organic solvents.
