Ethenethiourea, with the CAS number 96-45-7 and molecular formula C3H6SN2, is a white crystalline compound used primarily as a brightening agent in copper electroplating processes. The supplier lists its assay at 98%, indicating high chemical purity suitable for industrial plating baths. It is soluble in hot alcohol solutions, a property that facilitates its integration into acidic copper plating formulations when combined with co-additives such as M and SP.
This compound functions as a leveler and brightener in low-current-density zones of copper deposits, improving surface reflectivity and reducing grain roughness. In industry practice, it is typically dosed at 0.4 to 1.0 mg per liter of plating solution. Its stability under acidic conditions makes it compatible with standard sulfuric acid-copper sulfate baths, though it requires precise control of temperature and agitation to avoid decomposition. It is not a standalone additive but works synergistically with other brighteners in proprietary formulations.
Buyers in the electronics and hardware plating sectors use this chemical to achieve high-gloss finishes on printed circuit boards, connectors, and decorative components. It is supplied in sealed, moisture-resistant packaging, typically in 25 kg drums or 500 kg bulk containers. Trade terms are standard for industrial chemicals: FOB China port, payment via T/T, and lead time of 7 to 14 days after order confirmation. Buyers should verify compatibility with their existing plating chemistry before large-scale adoption.

Sourcing Ethenethiourea from Wuhan Excellent Voyage Chemical Co., Ltd. - China Import Guide
Before ordering, verify the supplier provides a Certificate of Analysis for each batch, confirming assay, moisture content, and absence of heavy metals like lead or cadmium. Request a sample for compatibility testing in your plating bath. Confirm the packaging is moisture-sealed and labeled with CAS number, hazard symbols, and batch code. Do not accept bulk shipments without documentation.
Trade terms are typically FOB Wuhan or Shanghai port. Lead time is 7 to 14 days after payment, but this is not guaranteed. Payment is usually via T/T in advance or L/C at sight. Incoterms should be clearly defined; avoid DDP unless the supplier has a local agent. Confirm container loading is performed under dry conditions to prevent moisture ingress during transit.
Quality checks should include visual inspection for color and crystallinity, moisture content via Karl Fischer, and assay via HPLC. Request a sample from each batch for independent lab testing. Ensure the supplier provides an SDS compliant with GHS and that the product is accompanied by export declarations and phytosanitary certificates if required. Retain samples for 12 months for dispute resolution.
