P-Toluenesulfonic Acid Suppliers, Manufacturers & Exporter
Chemical Bull is a sourcing partner for P-Toluenesulfonic Acid (PTSA) in India, serving chemical manufacturers, resin producers, pharmaceutical intermediate suppliers, coating manufacturers, and specialty chemical industries. We support industrial buyers with product sourcing, specification review, bulk supply enquiries, and commercial quotations based on their requirements.
P-Toluenesulfonic Acid, also known as 4-Toluenesulfonic Acid, 4-Methylbenzenesulfonic Acid, or PTSA, is a strong organic sulfonic acid widely used as an acid catalyst in chemical synthesis and industrial processing. It is valued for its catalytic activity and suitability for reactions where an organic acid catalyst is required.
Anhydrous P-Toluenesulfonic Acid has CAS No. 104-15-4, molecular formula C₇H₈O₃S, and molecular weight of approximately 172.20 g/mol. It is generally available as a crystalline solid. The monohydrate form has a different CAS number, 6192-52-5, and molecular weight of approximately 190.22 g/mol. Buyers should confirm the required form before placing an order.
P-Toluenesulfonic Acid is used in esterification, condensation, and other acid-catalysed reactions, as well as in resin curing, polymer processing, dye intermediates, and specialty chemical manufacturing. Its suitability depends on the reaction conditions, purity, moisture content, and compatibility with the process.
The required specification depends on anhydrous or monohydrate form, assay, appearance, moisture content, impurity profile, packaging, and intended application. Buyers should review the applicable COA, TDS, and MSDS/SDS before procurement.

P-Toluenesulfonic Acid is acidic and can cause serious irritation or corrosive injury depending on the concentration and exposure conditions. Avoid direct contact with skin and eyes and minimise dust exposure when handling solid grades. Follow the supplier's safety instructions, use suitable protective equipment, and store the material in compatible, tightly closed containers.
Applications of P-Toluenesulfonic Acid
Organic Synthesis and Acid Catalysis
P-Toluenesulfonic Acid uses as an acid catalyst in selected organic reactions, including esterification, transesterification, condensation, and acetalisation. It helps promote reactions where proton donation is required, with the appropriate loading determined by the reaction system.
Resin and Polymer Manufacturing
PTSA is used in selected resin manufacturing and curing processes, including certain phenolic, alkyd, and other acid-catalysed resin systems. The suitable grade and dosage depend on the resin chemistry, curing temperature, and required processing time.
Pharmaceutical and Fine Chemical Intermediates
P-Toluenesulfonic Acid is used in selected synthesis routes for pharmaceutical intermediates and specialty organic chemicals. Its role depends on the particular reaction and process specification; it should not be confused with a finished pharmaceutical ingredient.
Paints, Coatings and Adhesives
Selected coating, adhesive, and resin formulations use P-Toluenesulfonic Acid as a catalyst or curing agent. Compatibility, concentration, and handling requirements should be evaluated for the specific formulation.
Dye and Colour Chemical Manufacturing
P-Toluenesulfonic Acid is used in selected dye and specialty colour chemical manufacturing processes, particularly where acidic reaction conditions are required.
Electroplating and Metal Treatment
Certain industrial processes use P-Toluenesulfonic Acid or related sulfonic acid chemistry in metal treatment and electroplating systems. Suitability depends on the bath composition and process requirements.
Specialty Chemical Production
PTSA can be used in other industrial synthesis and processing applications that require an organic acid catalyst. Buyers should confirm that the grade and specification match the intended process.
