Solvent Yellow 33 is widely used as a dye in various industrial applications. It is commonly employed in the coloring of fuels, such as gasoline and diesel, to help differentiate between different types or grades of fuel. This aids in identification and prevents misuse. Additionally, it is utilized in the plastics industry to impart a yellow hue to products like PVC, polyethylene, and other synthetic materials. The dye is also found in inks, coatings, and waxes, where it provides consistent and vibrant coloration. Its stability and solubility in non-polar solvents make it a preferred choice for these applications.
