Para Toluene Sulphonic Acid (PTSA)

CAS Number: 104-15-4

Description

Para Toluene Sulphonic Acid (PTSA) is a strong organic acid available in both solid crystalline and liquid grades, widely used as a catalyst, intermediate, and resin hardener. With its high acidity, excellent solubility, and stability, PTSA is a preferred choice in organic synthesis, polymerization, and esterification reactions.

 

Compared to mineral acids, PTSA offers better selectivity, lower volatility, and ease of handling , making it a reliable industrial catalyst in pharmaceuticals, plastics, coatings, and specialty chemical manufacturing.
