Widely used as a dye in industrial applications, this compound imparts a strong red color to textiles and leather. It is particularly effective in dyeing polyester and cotton blends when applied with mordants. Commonly found in ink formulations for printing on synthetic fibers due to its good lightfastness and color intensity. Also utilized in the production of colored smoke and pyrotechnics because of its combustion properties that yield dense, vivid smoke. Limited in use for food or cosmetics due to poor biodegradability and potential release of aromatic amines.
