Product Description:
Used as a diazo-based dye in textile and leather industries, particularly for dyeing cotton, wool, and silk fabrics. Its structure allows strong binding to fibers, providing good color fastness and vibrant shades, typically in red, orange, or brown tones. Also employed in paper printing and as a coloring agent in some specialty inks. Shows pH-dependent color change, making it suitable for use in certain indicator applications. Limited use in biological staining due to its affinity for protein fibers.
