o-ANISIDINE ICSC: 0970
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
RED TO YELLOW OILY LIQUID, WITH CHARACTERISTIC ODOUR. TURNS BROWN ON EXPOSURE TO AIR.

CHEMICAL DANGERS:
The substance decomposes on burning producing toxic fumes of nitrogen oxides. Reacts with acids, acid anhydrides, acid chlorides, chloroformates and strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.1 ppm (as TWA) (A3) (skin) (ACGIH 1998).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion.

INHALATION RISK:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20C; on spraying or dispersing, however, much faster.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the blood, resulting in formation of methaemoglobin. The effects may be delayed. Medical observation is indicated. See Notes.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
This substance is possibly carcinogenic to humans.
PHYSICAL PROPERTIES
Boiling point: 213C
Melting point: 5C
Relative density (water = 1): 1.1
Solubility in water, g/100 ml: 1.5
Vapour pressure, kPa at 20C: 2
Relative vapour density (air = 1): 4.25
Relative density of the vapour/air-mixture at 20C (air = 1): 1.0
Flash point: 118C o.c.
Auto-ignition temperature: 415C
Octanol/water partition coefficient as log Pow: 1.18
ENVIRONMENTAL DATA
The substance is toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment.
NOTES
Depending on the degree of exposure, periodic medical examination is indicated. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Also consult ICSC #0971 p-Anisidine.
