Chemical Properties
amber liquid
Uses
Sulfallate is a selective pre-planting or pre-emergence herbicide.
General Description
Amber to dark amber liquid.
Air & Water Reactions
Insoluble in water. Thio and dithiocarbamates slowly decompose in aqueous solution to form carbon disulfide and methylamine or other amines. Such decompositions are accelerated by acids.
Reactivity Profile
SULFALLATE is incompatible with strong oxidizing agents .Also incompatible with alkalis. .
Fire Hazard
SULFALLATE is probably combustible.
Potential Exposure
A dithiocarbamate. The major use for sulfallate in the United States is as a preemergent selective herbicide to control certain annual grasses and broadleaf weeds around vegetable and fruit crops. Sulfallate has also been used for weed control among shrubbery and ornamental plants. Some dithiocarbamates have been used as rubber components
First aid
Skin Contact: Flood all areas of body that have contacted the substance with water. Don’t wait to remove contaminated clothing; do it under the water stream. Use soap to help assure removal. Isolate contaminated clothing when removed to prevent contact by others. Eye Contact: Remove any contact lenses at once. Flush eyes well with copious quantities of water or normal saline for at least 2030 minutes. Seek medical attention. Inhalation: Leave contaminated area immediately; breathe fresh air. Proper respiratory protection must be supplied to any rescuers. If coughing, difficult breathing or any other symptoms develop, seek medical attention at once, even if symptoms develop many hours after exposure. Ingestion: If convulsions are not present, give a glass or two of water or milk to dilute the substance. Assure that the person’s airway is unobstructed and contact a hospital or poison center immediately for advice on whether or not to induce vomiting.
Shipping
UN2771 Dithiocarbamate and Thiocarbamate pesticides, solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials. UN3082 Environmentally hazardous substances, liquid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.
Incompatibilities
Dithiocarbamate esters are combustible. They react violently with powerful oxidizers such as calcium hypochlorite. Poisonous gases are generated by the thermal decomposition of dithiocarbamate compounds, including carbon disulfide, oxides of sulfur, oxides of nitrogen, hydrogen sulfide, ammonia, and methylamine.Thio and dithiocarbamates slowly decompose in aqueous solution to form carbon disulfide and methylamine or other amines. Such decompositions are accelerated by acids. Flammable gases are generated by the combination of dithiocarbamate with aldehydes, nitrides, and hydrides. Dithiocarbamate are incompatible with acids, peroxides, and acid halides.
Waste Disposal
Small amounts may be decomposed by strong oxidizing agent. Large amounts should be incinerated in a unit with effluent gas scrubbing.
Definition
ChEBI: Sulfallate is a thiocarbonyl compound.
Carcinogenicity
Sulfallate is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.
