Disperse Violet 26 is primarily used as a dye in the textile industry for dyeing synthetic fibers such as polyester, acetate, and nylon. It provides a bright violet shade with good color fastness when applied under high-temperature dyeing processes. This dye is especially effective in deep shade dyeing due to its strong affinity for hydrophobic fibers.

It is also employed in the coloring of plastic materials and in some cases for dyeing leather. Due to its dispersibility in water, it can be easily applied in aqueous dye baths without the need for additional solvents. Disperse Violet 26 is valued for its uniform dyeing properties and resistance to fading from light and washing, making it suitable for use in apparel, home textiles, and industrial fabrics.
