4-AMINOBIPHENYL

ICSC: 0759

IMPORTANT DATA

PHYSICAL STATE; APPEARANCE:
COLOURLESS SOLID IN VARIOUS FORMS , WITH CHARACTERISTIC ODOUR. TURNS PURPLE ON EXPOSURE TO AIR.

CHEMICAL DANGERS:
On combustion, forms toxic gases. The solution in water is a weak base. Reacts with strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: A1 (skin) (ACGIH 1996).
MAK: skin absorption (H); Carcinogen category: 1 (DFG 2006).

ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

INHALATION RISK:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly by dispersing.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes. The substance may cause effects on the bladder, resulting in blood in urine.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
This substance is carcinogenic to humans.

PHYSICAL PROPERTIES

Boiling point: 302°C
Melting point: 53°C
Relative density (water = 1): 1.2
Solubility in water, g/100 ml at 25°C: 0.2

Flash point: 153°C c.c.
Auto-ignition temperature: 450°C
Octanol/water partition coefficient as log Pow: 2.8

ENVIRONMENTAL DATA

NOTES

Periodic medical examination is indicated. Special attention should be given to urine sediment and cytology. Do NOT take working clothes home. Card has been partially updated in August 2007: see Occupational Exposure Limits.
