Used as a dye in the textile industry for coloring wool, silk, and nylon fabrics, providing a bright red shade with good wash fastness. Commonly applied in batch dyeing processes where controlled pH and temperature ensure optimal color uptake. Also utilized in the production of ink formulations and as a staining agent in some biological and histological applications for microscopic examination. Its strong color intensity makes it suitable for use in low concentrations, reducing material costs in industrial processes.
