| Hazard Information | Back Directory | [Chemical Properties]
Reddish purple powder. Insoluble in water, ethanol, and organic solvents. Dark green in concentrated sulfuric acid, reddish purple upon dilution. Yellow in alkaline sodium sulfate solution, colorless in acidic solution. | [Uses]
Vat Voilet 3 has similar performance characteristics to Vat Red Violet (RH) (CI73385) and is a light-brittle dye. It is mainly used for dyeing cotton fibers and printing on cotton fabrics, exhibiting good affinity and leveling properties. It also provides good leveling and affinity when used for dyeing silk. It is also suitable for dyeing wool, nylon, and vinylon. It can be blended with bromoindigo and vat brown (RRD) to dye black, and can also be blended with vat bright pink (R), orange (RF), and scarlet (GGN). | [Preparation]
2,5-Dimethyl-4-chlorophenylmercaptoacetic acid with Chlorosulfonic acid cyclization, oxidation. This intermediate is chlorinated using the sulfonyl chloride route xylene (BIOS) derived. | [Properties and Applications]
