Direct Red 28 is widely used in the textile industry as a dye for coloring cotton, silk, and other cellulose-based fabrics. Its ability to bind directly to fibers without the need for a mordant makes it a convenient choice for producing vibrant red hues. Additionally, it is employed in the paper industry for dyeing paper products, providing consistent and durable coloration. In biological and histochemical studies, it serves as a staining agent to highlight specific tissues or cellular components under microscopic examination. Its stability and intense color also make it suitable for use in inks and coatings, where long-lasting and vivid results are desired.
