Thidiazuron Chemical Properties,Usage,Production

Chemical Properties

The pure product is a white odorless and tasteless crystalline solid. m.p.210～212.5°C (decomposition at 217°C), vapor pressure 4×10-9Pa) (25°C). Solubility at 25°C: dimethyl sulfoxide>500g/L, dimethylformamide>500g/L, cyclohexanone 21.5g/L, acetone 8g/L, methanol 4.5g/L, ethyl acetate 0.8 g/L, hexane 6mg/L, insoluble in aliphatic and aromatic hydrocarbons, solubility in water 31mg/L. The partition coefficient is 59 (pH=7.3). Stable below 200°C; stable to water at room temperature, half-life > 24d; half-life in soil < 60d.

Uses

Thidiazuron is a non-purine containing urea derivative with cytokinin activity. Thidiazuron is used as a cotton defoliant and a plant growth regulator in tissue culture.

Uses

Plant growth regulator used to defoliate cotton to facilitate harvesting.

Definition

ChEBI: Thidiazuron is a member of ureas.

General Description

Thidiazuron is a systemic herbicide, widely employed as an effective plant growth regulator and pre-harvest defoliant for crops such as cotton.

Agricultural Uses

Thidiazuron is substituted urea that is used to defoliate cotton plants. Thidiazuron, which has cytokinin activity, is one of the many harvesting aids needed in agriculture.

Agricultural Uses

Herbicide, Defoliant, Plant growth regulator: Used primarily as a cotton defoliant in order to increase the harvest yield. Not applied to food crops. Not approved for use in EU countries. Registered for use in the U.S. U.S. Maximum Allowable Residue Levels for Thidiazuron and its aniline-containing metabolites in or on the following food commodities: [40 CFR 180.403(a)]: cattle, fat 0.4 ppm; cattle, meat 0.4 ppm; cattle, meat byproducts 0.4 ppm; cotton, gin byproducts 24.0 ppm; cotton, undelinted seed 0.3 ppm; goat, fat 0.4 ppm; goat meat 0.4 ppm; goat, meat byproducts 0.4 ppm; hog, fat 0.4 ppm; hog, meat 0.4 ppm; hog, meat byproducts 0.4 ppm; horse, fat 0.4 ppm; horse, meat 0.4 ppm; horse, meat byproducts 0.4 ppm; milk 0.05 ppm; sheep, fat 0.4 ppm; sheep, meat 0.4 ppm; sheep, meat byproducts 0.4 ppm.

Safety Profile

Moderately toxic by ingestion. Experimental reproductive effects. When heated to decomposition it emits toxic fumes of SOx and NOx.

Environmental Fate

Soil. The reported half-life in soil is approximately 26–144 days (Hartley and Kidd, 1987).
Photolytic. Rapidly converted to the photoisomer, 1-phenyl-3-(1,2,5-thiadiazol-3- yl)urea (Worthing and Hance, 1991). When thidiazuron adsorbed by soil was exposed to UV light (λ <290 nm), 1-phenyl-3-(1,2,5-thiadiazol-3-yl)urea formed as the majo
