N-PHENYL-1,4-BENZENEDIAMINE ICSC: 1446
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
PURPLE CRYSTALLINE POWDER OR NEEDLES.

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 20C 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: 354C
Melting point: 75C
Density: 1.09 g/cm^3
Solubility in water, g/100 ml at 20C: 0.05
Vapour pressure, Pa at 20C: 0.000076
Flash point: 193C
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.
NOTES
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.
