Description
Lead(II) methanesulfonate (CAS 17570-76-2, EC 401-750-5), also known as plumbous methanesulfonate or lead methane sulfate, is an organolead salt formed from lead and methanesulfonic acid. It carries no assigned E-code and is handled under REACH regulations as a substance of very high concern due to its lead content.
In electronics manufacturing, it serves as a lead source in electroplating baths, where its high solubility in aqueous media enables uniform lead and lead-tin alloy deposition on circuit board contacts and connectors. In metalworking and automotive lubricant formulations, it functions as a corrosion inhibitor by forming a protective lead-based film on metal surfaces under boundary lubrication conditions.
This material is supplied as an oil-phase liquid and is available in industrial grades compliant with REACH registration requirements. Procurement teams should note mandatory SDS review and downstream user obligations under EU hazardous substance regulations. Packaging formats are confirmed at the time of order.
