SULPROFOS Chemical Properties,Uses,Production
Chemical Properties
Sulprofos is a tan colored liquid.
Uses
Sulprofos is used to control Lepidoptera, thrips and other insects in cotton, soya, tobacco, vegetables and tomatoes.
General Description
Tan-colored liquid with a sulfide-like odor.
Reactivity Profile
Organothiophosphates are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
Hazard
Cholinesterase inhibitor. Questionable carcinogen.
Safety Profile
Poison by ingestion. Moderately toxic by skin contact. When heated to decomposition it emits very toxic fumes of POx and SOx.
Potential Exposure
A potential danger to those involved in the manufacture, formulation, and application of this insecticide that is used for control of certain lepidopterous, dipterous, and hemipterous insects on cotton, etc.
Environmental Fate
Biological. From the first-order biotic and abiotic rate constants of sulprofos in estu-
arine water and sediment/water systems, the estimated biodegradation half-lives were
19.5–61.6 and 3.5–19 days, respectively (Walker et al., 1988).
Photolytic. When sulprofos was exposed to sunlight as deposits on cotton foliage, glass
surfaces and in aqueous solution, the insecticide degraded rapidly (half-life <2 days).
Irradiation of sulprofos in aqueous solution using UV light (λ >290
Chemical/Physical. Emits toxic oxides of sulfur and phosphorus when heated to
decomposition (Lewis, 1990).
Metabolic pathway
Sulprofos is an organophosphorus insecticide possessing a 4-(methylthio) phenyl group and as such its metabolic fate has much in common with fenthion with which it also has the phosphorothioate (P=S) group in common. The major route of sulprofos metabolism is by oxidation to the sulfoxide and more slowly to the sulfone. The additional route of bioactivation is through oxidative desulfuration to form the sulprofos oxon and all five oxidative metabolites (sulprofos sulfoxide, sulprofos sulfone, sulprofos oxon, sulprofos oxon sulfoxide and sulprofos oxon sulfone) have been detected in rats. Degradative metabolism by hydrolysis or oxidative dearylation to the phenols occurs rapidly. Stage II metabolism in mammals involves the rapid conjugation of the phenolic dearylation products. The fate of the S-propyl phosphorodithioate group has not apparently been reported.
Metabolism
Major metabolic routes are by oxidation to the sulfoxide and sulfone and oxidative desulfuration to the oxons. Detoxification by dearylation to the phenols occurs rapidly. Sulprofos is degraded in soil with a half-life ranging from a few days to several weeks, depending on the soil type.
Shipping
UN3018 Organophosphorus pesticides, liquid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
Incompatibilities
Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Strong oxidizers may cause release of toxic phosphorus oxides. Organophosphates, in the presence of strong reducing agents such as hydrides, may form highly toxic and flammable phosphine gas. Keep away from alkaline materials.
Waste Disposal
In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
