Used as a reagent in analytical chemistry for the detection of hydrogen sulfide due to its ability to form a black lead sulfide precipitate. Employed in the textile industry as a mordant in dyeing processes to help fix dyes on fabrics, particularly with natural dyes such as those from plants or indigo. Historically used in cosmetics, particularly in hair dyes, though this application has declined due to toxicity concerns. Served in the production of other lead compounds and in some specialized coating formulations. Occasionally used in laboratory settings for synthesis and qualitative inorganic analysis, such as precipitating sulfides in water samples. Its use is limited in modern applications because of the health and environmental risks associated with lead.
