P-Toluenesulphonic Acid (PTSA) Supplier in Malaysia
- Also known as
- P-Toluenesulfonic Acid
- Para Toluene Sulphonic Acid
- Para-Toluenesulfonic Acid
- 4-Methylbenzenesulfonic Acid
P-toluenesulphonic acid supplier for catalysis, resin, coating and synthesis buyers in Malaysia. Also written as p-toluenesulfonic acid, para toluene sulphonic acid or para-toluenesulfonic acid and abbreviated PTSA (C7H8O3S), it is a strong aromatic organic sulphonic acid used where a solid or solution acid catalyst is preferred.
Commercial supply covers monohydrate crystals, anhydrous solid, technical flakes and aqueous solutions. Hydration state, assay and form are set against the buyer's specification rather than a single fixed grade. Tosic acid, 4-methylbenzenesulfonic acid and toluene-4-sulfonic acid name the same product identity.
Manufacturers use PTSA in esterification and condensation catalysis, polymer and resin manufacture, alkyd and coating systems, foundry resin curing and selected detergent formulations. Pharmaceutical and fine-chemical routes may also call for it as a process acid or intermediate under the selected grade.
Send the required form or hydration state, application, target specification, quantity and delivery location with your enquiry. Availability, packing, documentation and delivery timing are confirmed with the quotation.

P-Toluenesulphonic Acid grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| PTSA monohydrate crystals | white to off-white crystalline solid (monohydrate) | assay and water of hydration confirmed against the required specification | General industrial acid catalysis, esterification, resin curing and process chemistry where commercial monohydrate PTSA is specified. | Confirm the required pack format with the quotation. |
| Anhydrous p-toluenesulphonic acid | anhydrous solid | assay and residual moisture confirmed against the required specification | Synthesis and catalysis routes that call for anhydrous PTSA rather than the monohydrate, including water-sensitive esterification or condensation steps. | Confirm the required pack format with the quotation. |
| Technical grade PTSA flakes | flakes or free-flowing solid | assay confirmed against the required technical specification | Resin and polymer manufacture, alkyd and coating systems, foundry resin curing and detergent or cleaning formulations that accept technical-grade solid PTSA. | Confirm the required pack format with the quotation. |
| Aqueous PTSA solution | clear aqueous liquid | concentration confirmed against the required specification | Process charging and formulation work where a liquid p-toluenesulphonic acid feed is preferred over dry monohydrate or anhydrous solid. | Confirm the required pack format with the quotation. |

P-Toluenesulphonic Acid applications
Safety and handling
- Classification
- corrosive
Store sealed in a cool, dry place away from bases and incompatible substances. Hygroscopic solid grades pick up moisture; use suitable acid-resistant handling equipment, gloves and eye protection, and follow the safety data for the quoted grade.
Common questions about p-toluenesulphonic acid
Is PTSA the same as p-toluenesulphonic acid?
Yes when the product is expanded correctly. PTSA is the common trade acronym for p-toluenesulphonic acid (also written p-toluenesulfonic acid or para toluene sulphonic acid). It is not LABSA, toluene, PTA, p-toluenesulfonamide or sodium p-toluenesulfonate. Name the full acid and form on the enquiry so the correct material is quoted.
Which PTSA form should I request, monohydrate or anhydrous?
Monohydrate crystals are the usual commercial solid for general catalysis, esterification and resin work. Anhydrous PTSA is chosen when the process limits water of hydration. Flakes and aqueous solutions suit selected resin, coating or formulation feeds. State hydration state, form and application so the suitable grade can be matched.
Is p-toluenesulfonic acid a different product from p-toluenesulphonic acid?
No. They are spelling variants of the same aromatic sulphonic acid. British sulphonic and US sulfonic forms, plus para toluene sulphonic acid, 4-methylbenzenesulfonic acid, toluene-4-sulfonic acid and tosic acid, refer to the same chemical identity. Hydration state still needs to be stated.
What is p-toluenesulphonic acid used for?
Buyers typically specify PTSA as an acid catalyst for esterification, condensation and resin curing, in polymer and alkyd or coating systems, in selected detergent formulations, and as a process intermediate in fine- chemical or pharmaceutical routes. Describe the process so the grade and form can be aligned with use.
How does PTSA differ from LABSA or sulphuric acid?
PTSA is a short aromatic sulphonic acid used mainly as a solid or solution catalyst. Linear alkylbenzene sulphonic acid (LABSA) is a long-chain surfactant acid for detergents, and sulphuric acid is a mineral acid. Keep them on separate enquiries; do not substitute one for another without a process review.
What details are needed for a p-toluenesulphonic acid price enquiry?
Provide the form or hydration state, application, target specification, quantity and delivery location. Mention preferred packing and any product documents required so the quotation can cover the full requirement.
