| | 2,5-Diaminotoluene sulfate Usage And Synthesis |
| Chemical Properties | White Redish Powder | | Uses | 2,5-Diaminotoluene sulfate is a primary intermediate in various permanent hair dyes. | | Definition | ChEBI: 2,5-diaminotoluene sulfate is an organic sulfate salt obtained by combining 2,5-diaminotoluene with one molar equivalent of sulfuric acid; occurs as an intermediate during hair dye formulation. It has a role as an allergen. It is an organic sulfate salt and a diamine. It is functionally related to a 2-methyl-1,4-phenylenediamine. | | General Description | 2,5-Diaminotoluene sulfate occurs as an intermediate during hair dye formulation. | | Flammability and Explosibility | Non flammable | | Safety Profile | Poison by ingestion and
intraperitoneal routes. Mutation data
reported. When heated to decomposition it
emits very toxic fumes of NOx and SOx. See
also SULFATES. |
