Import 3-Mercapto-1-Propane Sulfonic Acid, Sodium Salt — Buy in wholesale FOB from Supplier in China

3-Mercapto-1-propane sulfonic acid sodium salt (MPS, CAS 17636-10-1) is a thiol-functionalized organosulfonate with the molecular formula C3H7O3S2Na, supplied by Wuhan Silworld Chemical Co., Ltd. from Hubei province, China. This compound combines a terminal sulfonic acid group with a proximal mercaptan, conferring dual ionic and chelating functionality that distinguishes it from simpler alkyl sulfonates. The sodium salt form ensures complete water solubility, making it suitable for aqueous-phase industrial processes where organic solvents are undesirable. Wuhan Silworld offers this material in powder or aqueous solution formats for bulk procurement by mineral processing and surface treatment buyers.

The thiol moiety in MPS provides strong affinity for heavy metal cations, particularly copper, lead, and zinc ions, through soft-soft acid-base interactions. This chelating behaviour underpins its primary use as a selective collector in froth flotation of sulfide ores, where it enhances separation efficiency of chalcopyrite and galena from gangue minerals. In electroplating baths, MPS functions as a brightener and grain refiner for copper and nickel deposits, promoting fine-grained, ductile metal layers. The sulfonate group maintains solubility across wide pH ranges, typically pH 3 to 12, preventing precipitation in acidic or alkaline process liquors. Standard commercial grades typically assay 95% to 99% active content, with residual moisture below 1% for the solid form.

Primary buyers include mining reagent distributors, electroplating chemical formulators, and wastewater treatment operators. MPS is also employed in analytical chemistry as a metal masking agent and in polymer synthesis as a chain transfer regulator. Bulk sourcing from Wuhan Silworld requires confirmation of packaging format (typically 25 kg fibre drums or IBC tanks for solutions), available purity grades, and certificate of analysis provision. Buyers should verify shelf stability data, as thiol compounds are prone to oxidative dimerisation; nitrogen blanketing or antioxidant stabilisation may be specified. Incoterms, minimum order quantities, and lead times are not stated in the listing and must be confirmed directly with the supplier.

Wuhan Silworld Chemical Co., Ltd. is located at No.198 Jiangjun Road, Wuhan, Hubei province, 430033, China, operating from a chemical industry cluster in central China with established logistics access to Yangtze River ports and national rail networks. The company holds a Harbor trust tier classification on the marketplace, indicating a baseline verification level. Its response rate is recorded as 0.00% with an average response time of zero hours, which suggests either a new listing, inactive account, or data capture anomaly. Prospective buyers should note this lack of responsiveness signal and plan direct outreach accordingly.

The supplier's product portfolio centres on specialty and fine chemicals, with this listing representing their offering in thiochemicals for industrial mineral processing and metal surface treatment. No information is provided about manufacturing capacity, R&D facilities, quality management system certifications (such as ISO 9001), or export licensing. The company does not disclose years in operation, employee count, annual revenue, or named clients in the available profile. Buyers evaluating Wuhan Silworld should request a company profile, business licence, and references from comparable chemical purchasers before committing to trial orders.
