1,2,4-Tributylphosphorotrithioate Chemical Properties,Uses,Production

Description

DEF is a cholinesterase-inhibiting organophosphorus pesticide compound used as a cotton defoliant that was registered in 1960.DEF is a colorless to pale-yellow transparent liquid with a skunk-like odor.It is completely miscible with n-hexane, dichloromethane, toluene, and 2-propanol and has an octanol–water partition coefficient of 3.31×105 at 25°C. DEF toxicity is primarily attributed to inhibition of various esterases, including acetylcholinesterase (AChE), butyrylcholinesterase (BuChE), neuropathic target esterase (NTE), and carboxylesterase, resulting in increased accumulation of endogenous acetylcholine (ACh) in cholinergic nerve terminals and related effector organs.

Chemical Properties

Tribufos is a colorless to yellow liquid. Tribufos is relatively stable to acids and heat and is hydrolyzed slowly under alkaline conditions. Tribufos has a mercaptan or skunk-like odor. Tribufos has a mercaptan or skunk-like odor. Practically insoluble in water (2.3×10-4 g/ 100 mL); completely miscible in dichloromethane, n-hexane, 2-propanol, toluene.

Uses

1,2,4-Tributylphosphorotrithioate is a defoliant for cotton.

General Description

Colorless to pale yellow liquid with mercaptan-like odor. Insoluble in water; soluble in aliphatic, aromatic, and chlorinated hydrocarbons.. Used as a growth regulator.

Air & Water Reactions

Insoluble in water. Hydrolyzed slowly by alkaline conditions.

Reactivity Profile

An organophosphate derivative. Organophosphates 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.

Agricultural Uses

Herbicide, Defoliant, Plant growth regulator: Tribufos is an organophosphate defoliant used for cotton crops. It is specifically used to defoliate cotton in preparation for machine harvesting. It was first registered in the United States in 1961. Not approved for use in EU countries . Registered for use in the U.S.

Trade name

B-1776®; BUTIFOS®; BUTIPHOS®[C]; CHEMAGRO® 1776; CHEMAGRO® B-1776; DE- GREEN®; DEF®; DEF DEFOLIANT®; DELEAFDEFOLIANT®; EASY OFF®-D; E-Z-OFF® D; FOLEX® 6EC FOS-FALL® A; ORTHO® phosphate defoliant

Safety Profile

A poison by ingestion, skin contact, and intraperitoneal routes. Experimental reproductive effects. Animal experiments show an anti-cholinesterase effect. When heated to decomposition it emits toxic fumes of PO, and SO,. See also PARATHION, PHOSPHATES, ESTERS, and SULFATES.

Carcinogenicity

No carcinogenic effects occurred when rats were given diets with 0, 4, 40, or 320 ppm tribufos (equivalent to 0.0, 0.2, 1.8, and 16.8 mg/kg/day in males and 0.0, 0.2, 2.3, and 21.1 mg/kg/day in females, respectively) for 2 years .
In a carcinogenicity study, mice were fed diets containing tribufos at doses of 0, 10, 50, or 250 ppm (equivalent to 0.0, 1.64, 8.28, or 48.02 mg/kg/day in males and 0.0, 2.08, 11.14, or 63.4 mg/kg/day in females) for 90 weeks . Carcinogenic effects were evident at 250 ppm (48.02 mg/kg/day in males and 63.4 mg/kg/day in females). Males exhibited a statistically significant increase in hemangiosarcomas and adenocarcinomas of the small intestines and females exhibited a statistically significant increase in alveolar/bronchiolar adenomas.

Environmental Fate

Soil. Hydrolyzes in soil to ethyl mercaptan, carbon dioxide and diisobutylamine (Hartley and Kidd, 1987). Butylate is probably subject to degradation of soil microorganisms. It was reported that butylate may degrade via hydrolysis of the ester linkage forming the corresponding mercaptan (ethyl mercaptan), alkylamine (diisobutylamine) and carbon dioxide. Transthiolation and oxidation of the mercaptan forms the alcohol which may further oxidize to afford a metabolic pool (Kaufman, 1967). Somasundaram and Coats (1991) reported butylate in soils is oxidized to the corresponding sulfoxide. The reported half-life in soil is approximately 1.5–10 weeks (Worthing and Hance, 1991). The reported half-life of butylate in a loam soil at 21–27°C was 3 weeks (Humburg et al., 1989). Residual activity in soil is limited to approximately 4 months (Hartley and Kidd, 1987).
Groundwater. According to the U.S. EPA (1986) butylate has a high potential to leach to groundwater.
Plant. In plants, butylate is metabolized to carbon dioxide, diisobutylamine, fatty acids, conjugates of amines and other compounds (Hartley and Kidd, 1987; Humburg et al., 1989).
