General Description: A brown or colorless crystalline solid with a pungent odor. More dense than water and nearly insoluble in water. Toxic by inhalation, skin absorption, or ingestion. Used as a pesticide, fungicide or herbicide.
Air & Water: Reactions Sightly soluble in water. Slowly hydrolyzes to form sulfur dioxide and a diol; hydrolyzes more rapidly under basic or acidic conditions.
Reactivity Profile Thiosulfan is an organochlorine, cyclodiene derivative. Thiosulfan is also a sulfite ester. Halogenated aliphatic or cyclic alkane compounds are moderately or very reactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. As Thiosulfan is rather highly substituted Thiosulfan may be resistant to reaction. However, materials in this group are incompatible with strong oxidizing and reducing agents. Also, they may be incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides. As an ester, Thiosulfan will hydrolyze to form sulfur dioxide and diol; reaction is more rapid under basic conditions.
Health Hazard :Thiosulfan is very toxic. The probable oral lethal dose is 50 to 500 mg/kg, or 1 teaspoonful to 1 ounce for a 150 lb. person.
Fire Hazard :Container may explode in heat of fire. Fire or run off from fire control water may release irritating or poisonous gases. Slowly oxidizes in air. Do not store at temperature below 20F.
