| 3,4-Diaminotoluene Usage And Synthesis |
| Chemical Properties | Off-white small blocks |
| Usage | 5-Methylbenzotriazole intermediate. |
| General Description | A colorless to brownish purple crystalline solid. Toxic by ingestion and inhalation and an irritant to skin and eyes. Soluble in water, alcohol and ether. Decomposes to emit toxic oxides of nitrogen when heated to high temperature. Used in making dyes. |
| Air & Water Reactions | Insoluble in water. |
| Reactivity Profile | 3,4-Diaminotoluene neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides. |
| Fire Hazard | Flash point data for 3,4-Diaminotoluene are not available. 3,4-Diaminotoluene is probably combustible. |
