P-Toluenesulfonic Anhydride
Shanghai Yongzeng Chemical Co., Ltd. supplies P‑Toluenesulfonic Anhydride, a white crystalline organic compound with formula C14H14O5S2 and CAS 4124‑41‑8. The reagent is offered in high‑purity grade, suitable for sensitive synthetic processes. It is packaged in standard industrial drums with a certificate of analysis accompanying each batch. The supplier lists the material as stable under normal storage conditions and soluble in common organic solvents.
In the chemical manufacturing sector, P‑Toluenesulfonic Anhydride is typically supplied with purity levels of 95 %‑99 % for pharmaceutical use, which aligns with the grade described by the supplier. The anhydride form provides greater stability than the corresponding acid, a standard advantage recognised in esterification and sulfonylation reactions. Typical handling guidelines advise storage below 30 °C and protection from moisture, reflecting standard safety data for this class of sulfonic anhydrides. Bulk shipments often use 200 L steel drums, a common industry practice for bulk organic reagents.
The compound is employed as a catalyst and reagent in the synthesis of pharmaceuticals, agrochemicals, specialty coatings and polymer precursors. Importers in these sectors value the consistent purity and the availability of analysis certificates for regulatory compliance. Trade terms are negotiable, with FOB shipping and T/T payment mentioned, and buyers should confirm exact MOQ and lead time directly with the supplier.

Sourcing P-Toluenesulfonic Anhydride from Shanghai Yongzeng Chemical Co., Ltd. - China Import Guide
Before placing an order, importers should verify the exact purity percentage, request the latest certificate of analysis and confirm that the supplier’s quality management system meets the buyer’s regulatory requirements. Because the listed response rate is zero, establishing a reliable communication channel early in the negotiation is advisable. Any claimed certifications should be validated with copies of the relevant certificates before commitment.
Logistics planning should include confirmation of the shipping port in Shanghai, the preferred Incoterm (FOB as indicated) and the expected lead time, which the supplier has not disclosed publicly. Buyers need to agree on payment terms, typically T/T, and ensure that bank details are verified to avoid fraud. Clarifying packaging size - standard 200 L drums - and arranging appropriate freight forwarding will help prevent delays.
Quality assurance relies on pre‑shipment inspection, preferably by a third‑party laboratory, to verify purity, moisture content and absence of contaminants. Importers should request the inspection report together with the certificate of analysis before final acceptance. Keeping records of all documentation, including the supplier’s address, COA and shipping documents, will facilitate customs clearance and downstream quality control.
