Acid Black 1(Cat No.: M071345), also known as Naphthol Blue Black or C.I. 20470, is an anionic azo dye used primarily in textile dyeing, paper coloring, and as a biological stain. It appears as a dark blue to black powder and is water-soluble due to its sulfonate groups. In histology and protein electrophoresis, Acid Black 1 binds to proteins for visualization. Its strong colorfastness and high affinity for protein fibers make it valuable in both industrial and laboratory staining applications.
