2-Thiouracil
2-Thiouracil is a heterocyclic pyrimidine derivative with the molecular formula C4H4N2OS, supplied here by Wuhan Silworld Chemical Co., Ltd. from Wuhan, Hubei, China. The compound is used as a pharmaceutical intermediate and as an antithyroid agent in drug manufacturing, and it also serves as a reagent in organic synthesis research. Typical commercial-grade material is specified at 98% or higher purity, which is the standard benchmark for pharmaceutical and research applications.
The substance is a solid at room temperature, typically supplied as a white to off-white crystalline powder. Its molecular weight is approximately 128.15 g/mol, and it has a melting point in the region of 330-340 C with decomposition. Standard packaging for bulk fine chemicals of this type is 25 kg fibre drums with polyethylene liners, though bulk bags may be available for larger orders. Storage should be in a cool, dry, well-ventilated area away from strong oxidisers, which is the standard handling protocol for thiol-containing heterocycles.
Buyers of 2-Thiouracil include pharmaceutical manufacturers, contract research organisations and academic laboratories working on antithyroid drug development or pyrimidine chemistry. Wuhan Silworld Chemical Co., Ltd. is based at No.198 Jiangjun Road, Wuhan 430033, and the listing references FOB and CIF shipping terms with payment by L/C or T/T. Exact MOQ, per-kilogram pricing and lead time are not published, so importers should request a quotation that includes batch-specific certificates of analysis before committing to an order.

Wuhan Silworld Chemical Co., Ltd. is located at No.198 Jiangjun Road, Wuhan 430033, Hubei, China. The supplier's platform profile shows a 'harbor' trust tier, which indicates a basic level of platform verification. The listing does not disclose the company's year of establishment, number of employees, production capacity or export history, so buyers conducting due diligence should request these details directly from the supplier.
The platform shows a response rate of 0.00% and an average response time of 0 hours, meaning there is no recorded enquiry history through the listing interface. This may simply reflect low platform traffic rather than the company's actual responsiveness. Buyers should reach out by email or the contact details on the supplier's own website and allow a reasonable window for a first reply. The listing references ISO and SGS certifications, but these are not verified on the platform profile, so request copies of any certificates and confirm their validity with the issuing body before relying on them.
2-Thiouracil is a heterocyclic pyrimidine derivative widely used as a pharmaceutical intermediate and antithyroid agent in drug manufacturing and organic synthesis research.

Sourcing 2-Thiouracil from Wuhan Silworld Chemical Co., Ltd. - China Import Guide
Before ordering 2-Thiouracil from Wuhan Silworld Chemical Co., Ltd., request a current certificate of analysis for the batch that will be shipped. The COA should confirm purity, identify any impurities above reporting thresholds, and list moisture content. Compare these values against your process requirements or your own in-house specifications. If the supplier cannot provide a batch-specific COA, consider sourcing from a supplier who can, as this document is essential for pharmaceutical and research-grade materials.
Shipping fine chemicals internationally requires careful attention to documentation and packaging. Confirm that the supplier will provide a material safety data sheet in English, a commercial invoice with the correct CAS number and HS code, and a packing list that matches the actual shipment. For sea freight, FOB Wuhan typically means the goods are delivered to the nearest port, which for Wuhan is usually Shanghai or another Yangtze River port with container services. Ask the supplier which port they will use and request a CIF quote to your destination port if you want them to handle freight and insurance.
On receipt, inspect the drums for signs of damage, leakage or tampering before signing the carrier's delivery receipt. Store the material in a cool, dry, well-ventilated warehouse away from incompatible substances as indicated on the SDS. Retain a sample from the delivered batch for your own quality testing, and compare the results against the COA provided by the supplier. If there is any discrepancy between the COA and your test results, notify the supplier immediately and document the issue with photographs and test reports.
