Chemical Properties |
Light Beige Purple Liquid |
Usage |
A carcinogenic and toxic aromatic amine contained in hair dye, henna and dyed hair samples. |
General Description |
A clear colorless or light yellow liquid. May become reddish brown on exposure to air and light. Flash point 185°F. Has about the same density as water and is very slightly soluble in water. Vapors are heavier than air. Confirmed carcinogen. |
Air & Water Reactions |
Becomes reddish brown upon exposure to air and light [Hawley]. Slightly soluble in water. |
Reactivity Profile |
o-Toluidine 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. Emits very toxic oxides of nitrogen when heated to decomposition. Undergoes a hypergolic reaction with red fuming nitric acid [Kit and Evered, 1960, p. 239, 242]. |
Health Hazard |
Absorption of toxic quantities by any route causes cyanosis (blue discoloration of lips, nails, skin); nausea, vomiting, and coma may follow. Repeated inhalation of low concentrations may cause pallor, low-grade secondary anemia, fatigability, and loss of appetite. Contact with eyes causes irritation. |
Fire Hazard |
Special Hazards of Combustion Products: Toxic oxides of nitrogen and flammable vapors may form in fire. |
