description Product Description
Used historically in the production of dyes for textiles, paper, and leather, it played a significant role in creating vibrant colors. It was also employed in chemical laboratories as a reagent for detecting blood and certain ions. However, due to its carcinogenic properties, its use has been heavily restricted or banned in many countries, and safer alternatives are now preferred in industrial and laboratory applications.
