Used primarily in research laboratories as a source of lead ions in chemical synthesis and electrochemical studies. It serves as a precursor in the preparation of other lead-containing compounds and materials. Due to its oxidizing nature, it can participate in redox reactions and is sometimes employed in pyrotechnic compositions or energetic materials research. Its high solubility in water makes it suitable for aqueous solution-based applications where controlled release of lead(II) ions is required. Handle with extreme care due to toxicity of lead and the potential for explosive reactions when in contact with organic materials or reducing agents.
