Widely used as an azo dye in industrial coloring applications, this compound imparts a strong red to orange-red hue to textiles, plastics, and coatings. Its conjugated azo structure provides excellent lightfastness and color intensity, making it suitable for synthetic fibers and polymer systems. It is also employed in the formulation of printing inks and pigments where thermal stability and vibrant shade are required. Additionally, due to its pH-sensitive chromogenic properties, it finds use as a colorimetric indicator in certain analytical systems. However, like many azo compounds, its application is sometimes limited by regulatory concerns over potential degradation into aromatic amines.
