| Molecular Formula | C21H28N6O6S |
| Molar Mass | 492.55 |
| Physical and Chemical Properties | The chemical properties are easily soluble in water, and the aqueous solution is blue-red. The dye is vermilion in concentrated sulfuric acid and pink after dilution. The dyed acrylic fiber is dark blue and red, dyed at 120 ℃ with no change in color and light. |
| Use | Uses Cationic Red 5BL is suitable for acrylic dyeing, can be used for direct printing of acrylic and diacetate fabrics, and can be white in light color. The dye depth is good. It can be combined with cationic golden GL (C.I.Basic Yellow 28) and cationic blue NBL to dye various dark colors. |
| Raw Materials | SULFATE STANDARD N-Ethylaniline TMA(TRIMETHYLAMINE) (N-ethylanilinoethyl)trimethylammonium methyl sulfate 5-Nitroanthranilonitrile |
Using 2-cyano-4-nitroaniline and (2-N-ethylanilinoethyl) trimethylammonium methyl sulfate as raw materials, the 2-cyano-4-nitroaniline is first diazotized, and then coupled with the latter to obtain the product. The finished product is filtered and dried.
