International Chemical Safety Cards N-PHENYL-1,4-BENZENEDIAMINE ICSC: 1446 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: PURPLE CRYSTALLINE POWDER OR NEEDLES. PHYSICAL DANGERS: CHEMICAL DANGERS: On combustion, forms toxic fumes ( carbon monoxide , nitrogen oxides ). Reacts with strong acids and strong oxidants . OCCUPATIONAL EXPOSURE LIMITS: TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation and by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered. EFFECTS OF SHORT-TERM EXPOSURE: The substance is irritating to the skin and the eyes . The substance may cause effects on the blood following ingestion , resulting in the formation of methaemoglobin. Medical observation is indicated. The effects may be delayed. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization. PHYSICAL PROPERTIES Boiling point: 354°C Melting point: 75°C Density: 1.09 g/cm3 Solubility in water, g/100 ml at 20°C: 0.05 Vapour pressure, Pa at 20°C: 0.000076 Flash point: 193°C Octanol/water partition coefficient as log Pow: 2.4 (calculated) ENVIRONMENTAL DATA This substance may be hazardous in the environment; special attention should be given to aquatic organisms. N O T E S Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Do NOT take working clothes home. UN 3077 is for the molten substance. ADDITIONAL INFORMATION ICSC: 1446 N-PHENYL-1,4-BENZENEDIAMINE (C) IPCS, CEC, 1994
