Used primarily in electroplating baths as a source of lead ions, especially in the electronics industry for producing lead-tin solder deposits on printed circuit boards. Its high solubility in aqueous and organic electrolytes makes it suitable for use in methanesulfonic acid-based plating systems, which are less hazardous than traditional fluoroboric or nitrate-based baths. Also employed in the synthesis of other lead-containing compounds used in specialty chemicals and catalysts. Due to lead's toxicity, handling requires strict environmental and safety controls.
