About Direct Blue 71
Direct Blue 71 (CAS 4399-55-7) is a synthetic polyazo dye belonging to the direct dye class.

In its powder form, it is highly soluble in water, making it a preferred choice for aqueous dyeing processes.
In the Indian market, this dye is extensively utilized by textile processing units in hubs like Tirupur, Surat, and Ahmedabad for dyeing cotton fabrics and yarns. It is also a staple in the paper and pulp industry for producing high-quality colored paper, and it serves as a critical reagent in biological research laboratories for staining tissues and cellular structures.
