Used primarily in analytical chemistry for qualitative detection of sulfide ions due to its ability to form lead sulfide, a black precipitate. Also employed in specialized electroplating baths where lead-based coatings are required for corrosion resistance. Serves as a precursor in the synthesis of other lead compounds in laboratory settings. Limited use in organic synthesis as a mild reagent in formylation reactions. Due to toxicity, applications are restricted and handled under controlled conditions.
