Product Description
P-toluene sulfonic acid(PTSA) is an organic compound. It is a white extremely hygroscopic solid that is soluble in water, alcohols, and other polar organic solvents. PTSA is a strong organic acid. It is about one million times stronger than benzoic acid. It is one of the few strong acids that is solid and therefore is conveniently weighted and stored.
