P-Toluenesulfonic Acid

p-Toluenesulfonic acid (PTSA) is a white to off-white crystalline solid with a faint, characteristic odor; it is non-volatile, hygroscopic, and melts at approximately 106–107 °C. It is an aromatic organic sulfonic acid and a widely used Brønsted acid catalyst and reagent. PTSA serves primarily as a versatile catalyst and intermediate in organic synthesis, particularly in esterifications, acetal formations, and dehydration reactions. Its principal applications span pharmaceuticals (e.g., active pharmaceutical ingredient synthesis), agrochemicals (e.g., herbicide and insecticide intermediates), dyes, and polymer production (e.g., polyester and polyacetal resins). It is also employed in coatings, adhesives, and specialty chemical manufacturing.

(1) For chemical reagents, but also for dyes, organic synthesis.(2) Used as the intermediates of medicine (such as doxycycline), pesticides (such as dicofol), dyes. Also used in detergents, plastics, coatings and so on.(3) For medicine, pesticides, dyes and detergents, but also for plastics and printing coatings.(4) Widely used in the catalyst synthetic medicine, pesticides, polymerization of the stabilizer and organic synthesis (esters, etc.). Also used as medicine, paint intermediates and resin curing agent.
Colorless monoclinic sheet or columnar crystals. Soluble in ethanol and ether, slightly soluble in water and hot benzene.
