Applications:

• Commonly used as a supporting electrolyte for the deposition of polypyrrole membranes. It is also employed as a solute in studies on the performance of resin particles.
• Sodium p-toluenesulfonate can be used for the efficient cleaning of explosive residues.
• In liquid detergents, it acts as a solubilizer. Its addition helps reduce viscosity and turbidity.
• Sodium P-Toluenesulfonate is widely used in organic synthesis. The pharmaceutical industry is involved in the synthesis of doxycycline, panentin, naproxen, and intermediates for amoxicillin and cephalexin production.
• Functions as a slurry conditioner in the chemical and synthetic detergent industries. When used as a water-retaining solvent in powder detergents, it increases water content and improves fluidity, texture, and resistance to clumping.
