IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS TO BROWN CRYSTALLINE POWDER

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic fumes including hydrogen chloride. The solution in water is a weak acid. Attacks some forms of coatings and metals in the presence of moisture.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established. MAK not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion.

INHALATION RISK:
A harmful concentration of airborne particles can be reached quickly on spraying or when dispersed, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes, the skin and the respiratory tract.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
(See Notes).
PHYSICAL PROPERTIES
Melting point: 94C
Density: 1.28 g/cm
Solubility in water, g/100 ml at 25C: 0.07
Vapour pressure, Pa at 22.5C: 0.08
Octanol/water partition coefficient as log Pow: 1.17
ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms. This substance does enter the environment under normal use. Great care, however, should be given to avoid any additional release, e.g. through inappropriate disposal.
NOTES
Mecoprop is a chlorophenoxy-herbicide which, as a group, has been classified by IARC (1987) as possibly carcinogenic to humans, but the data on this specific substance are inconclusive. Carrier solvents used in commercial formulations may change physical and toxicological properties. Other CAS number 7085-19-0.
