Thiodicarb Chemical Properties,Uses,Production
Description
Thiodicarb, 3,7,9,13-tetramethyl-5,11- dioxa-2,8,14-trithia-4,7,9,12-tetra-azapentadeca-3,12-di ene-6,10-dione (IUPAC), consists of colorless crystals, which are sparingly soluble in water, readily soluble in dichloromethane, acetone, methanol, and xylene. Thiodicarb is produced by reaction of N,N -thiobis(methylcarbamic acid fluoride) with 2-methylthioacetaldoxim in the presence of a base.
Uses
Thiodicarb is used as an insecticide.
General Description
Colorless to pale tan crystals. Non corrosive. Used as an insecticide.
Air & Water Reactions
Hydrolyzed by strong acid or base.
Reactivity Profile
A carbamate derivative. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates.
Agricultural Uses
Insecticide, Molluscicide, Ovicide: Not approved for use in EU countries. Registered for use in the U.S. Thiodicarb is used primarily on cotton, sweet corn, and soybeans. The remaining usage is spread among leafy vegetables, cole crops, ornamentals, and other minor use sites. Thiodicarb acts as an ovicide against cotton bollworms and budworms.
Trade name
CGA® 45156; CHIPCO[C]; DICARBOSULF®; DICARBASULF®; LARVIN®; LEPICRON®; SEMEVIN®; NIVRAL®; UC-51762®; UC 51769®; UC 80502®
Environmental Fate
Soil. Under aerobic and anaerobic soil conditions, thiodicarb degrades to methomyl and methomyl oxime (Hartley and Kidd, 1987). The reported half-life in various soils is 3–8 days (Hartley and Kidd, 1987).
Metabolic pathway
The initial metabolic reaction of thiodicarb in soils, plants and animals is the hydrolytic or thiolytic cleavage of the N-S bond to methomyl. The subsequent metabolic pathway of methomyl involves hydrolysis / elimination reactions to yield S-methyl-N-hydroxythioacetimidate and ultimately acetonitrile and CO2 as the major terminal products. The metabolic pathways of thiodicarb are presented in Scheme l. See also the methomyl entry.
