p-Toluenesulfonic Acid Monohydrate (p-TsOH·H₂O)
p-Toluenesulfonic acid (p-TsOH·H₂O) is a strong organic acid widely used as a catalyst and reagent in organic synthesis. It typically appears as a white crystalline solid and exhibits high solubility in water, alcohols, and other polar organic solvents. Moreover, due to its non-oxidizing nature and strong acidity, it serves as a safer and more selective alternative to mineral acids like sulfuric acid.
