Product Name:Direct Violet 9
English Name:Direct Violet 9
CAS No.:6227-14-1
Aliases:Direct Fast Violet BK, C.I. Direct Violet 9 disodium salt, Direct Violet MB
Molecular Formula:C31H27N5Na2O7S2
Physical Properties:Blue-violet powder. Density 1.709 g/cm³ at 20°C; vapor pressure 0 Pa at 25°C. Soluble in water, giving a red-violet solution; slightly soluble in ethanol; insoluble in other organic solvents. Shows blue-green color in concentrated sulfuric acid, with purple precipitate on dilution; red-brown in nitric acid. The dye solution gives purple precipitate with concentrated hydrochloric acid and with concentrated sodium hydroxide solution. Water solubility is 6.23 g/L at 20°C; octanol-water partition coefficient logP is -2.165 at 20°C.
Uses:Direct Violet 9 is a direct dye used for dyeing and printing of cellulose fibers such as cotton, linen, and viscose, as well as for coloring paper. In scientific research, it is used as a biological stain.
