2-MERCAPTOIMIDAZOLINE ICSC: 1148
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
WHITE TO PALE GREEN CRYSTALS.

CHEMICAL DANGERS:
The substance decomposes on heating or on burning producing toxic and irritating fumes including nitrogen oxides and sulfur oxides.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: Carcinogen category: 3B; (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and through the skin.

INHALATION RISK:
Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the thyroid and liver, resulting in impaired functions. Animal tests show that this substance possibly causes malformations in human babies.
PHYSICAL PROPERTIES
Melting point: 203-204C
Solubility in water, g/100 ml at 30C: 2 (moderate)
Flash point: 252C
Octanol/water partition coefficient as log Pow: -0.66 (calculated)
