CAS 104-15-4
:Benzenesulfonic acid, 4-methyl-
Description:
4-Methylbenzenesulfonic acid, also known as p-toluenesulfonic acid, is an aromatic sulfonic acid characterized by the presence of a methyl group attached to the benzene ring at the para position relative to the sulfonic acid group (-SO3H). This compound is a colorless to pale yellow solid that is highly soluble in water and polar organic solvents. It exhibits strong acidity, making it a useful reagent in organic synthesis, particularly as a catalyst in esterification and other reactions requiring protonation. The sulfonic acid group enhances the compound's ability to act as a strong acid, and its aromatic structure contributes to its stability. Additionally, 4-methylbenzenesulfonic acid is often used in the production of surfactants, dyes, and pharmaceuticals. Safety precautions should be taken when handling this compound, as it can cause irritation to the skin, eyes, and respiratory tract. Overall, its unique properties make it a valuable substance in various chemical applications.
