Product Information

• Name: 4-Bromobenzenesulfonic acid
• Brand: Biosynth
• Description: 4-Bromobenzenesulfonic acid is a chemical used in the synthesis of organic molecules. It is an intermediate in the production of cyclopropylboronic acid, which is used as a building block in various organic syntheses. 4-Bromobenzenesulfonic acid can be prepared by reacting pyridine with acetic anhydride and then adding sodium carbonate to remove water. This reaction produces a molecule with two acid groups that are nucleophilic and can react with carboxylic acids to form esters. The yield for this reaction is high and it does not require any special equipment or conditions. This chemical is also used as a linker for other compounds during synthesis reactions, such as diazonium salts or dioxane. 4-Bromobenzenesulfonic acid reacts with triethylphosphite to give disulfides, which are important for protein structure.
