Used as a mordant in textile dyeing to help fix dyes on fabrics, especially with natural fibers. Commonly employed in the preparation of other lead compounds for industrial applications. Historically used in cosmetics and hair dyes, though this practice has declined due to toxicity concerns. Occasionally used in laboratory settings as a reagent for qualitative analysis, such as detecting the presence of certain anions. Also found in some specialized coating formulations and in the production of pigments, despite limited use due to environmental and health regulations.
