p-Toluenesulfonic acid

p-Toluenesulfonic acid (p-TsOH) is a strong organic acid commonly used in chemical synthesis. It has a benzene ring with a methyl group and a sulfonic acid group attached. Its primary role is to catalyze reactions, such as breaking down complex molecules or helping form new compounds, especially in organic chemistry labs. Because it’s potent, it must be handled with care. It’s valued for its high acidity, stability, and solubility in organic solvents, making it an effective and versatile catalyst in various chemical processes, including pharmaceuticals, dyes, and polymers manufacturing.
