Colorless to reddish-violet solid. Used in the production of methylene blue and photographic developer. Used as a chemical intermediate for dyes and diazonium chloride salts and as an analytical reagent to detect chloroamine in water.
Reaktivität anzeigen
N,N-Dimethyl-1,4-phenylenediamine 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. Incompatible with strong oxidizers, strong acids and acid anhydrides. Also incompatible with alkalis .
Hazard
Toxic by ingestion or inhalation of vapor.
Health Hazard
Lowest toxic dose with skin effect is 14 mg/kg. Irritant to skin and eyes.
Brandgefahr
When heated to decomposition, N,N-Dimethyl-1,4-phenylenediamine emits toxic fumes of nitrogen oxides.
Erste Hilfe
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin,remove contaminated clothing and wash immediately withsoap and water. Seek medical attention immediately. If thischemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart actionhas stopped. Transfer promptly to a medical facility. Whenthis chemical has been swallowed, get medical attention.Give large quantities of water and induce vomiting. Do notmake an unconscious person vomit.
Lager
