Description
1-(5-tert-Butyl-1,3,4-thiadiazol-2-yl)-1,3-dimethylurea, commonly known as Tebuthiuron, is a non-selective, broad-spectrum herbicide. It is a chemical compound with the molecular formula C10H19N3O2S and is characterized by its ability to control various types of weeds, including woody and herbaceous plants.
Uses
Used in Agricultural Applications:
1-(5-tert-Butyl-1,3,4-thiadiazol-2-yl)-1,3-dimethylurea is used as a herbicide for controlling weeds in non-cropland areas, rangelands, rights-of-way, and industrial sites. It is effective against a wide range of plant species, including alfalfa, bluegrasses, chickweed, clover, dock, goldenrod, and mullein.
Used in Non-cropland Management:
1-(5-tert-Butyl-1,3,4-thiadiazol-2-yl)-1,3-dimethylurea is used as a nonselective herbicide to control herbaceous and woody plants in non-cropland areas. It helps in maintaining the land free from unwanted vegetation, which can be beneficial for various purposes such as construction, infrastructure development, and land management.
Used in Grassland Management:
In grasslands, 1-(5-tert-Butyl-1,3,4-thiadiazol-2-yl)-1,3-dimethylurea is used as a herbicide to control woody and herbaceous plants, ensuring the proper growth and maintenance of grasslands.
Used in Sugar Cane Cultivation:
1-(5-tert-Butyl-1,3,4-thiadiazol-2-yl)-1,3-dimethylurea is used as a herbicide in sugar cane cultivation to control weeds and other competing plants, which can negatively impact sugar cane growth and yield.

Environmental Fate
Soil. In microbially active soils, tebuthiuron is degraded via demethylation. The average
half-life in soil 12–15 months in areas receiving 60 inches of rainfall a year (Humburg et
al., 1989).When tebuthiuron was applied to a rangeland at a rate of 0.84 kg/ha, 38% remained
after 21 months (Emmerich et al., 1984).Groundwater . According to the U.S. EPA (1986) tebuthiuron has a high potential to
leach to groundwater .Plant. Degrades in plants via N-demethylation and hydroxylation of the t-butyl
sidechain (Hartley and Kidd, 1987; Humburg et al., 1989).
Check Digit Verification of cas no
The CAS Registry Mumber 34014-18-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,0,1 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 34014-18:
(7*3)+(6*4)+(5*0)+(4*1)+(3*4)+(2*1)+(1*8)=71
71 % 10 = 1
So 34014-18-1 is a valid CAS Registry Number.

Paragraph 0031; 0037-0040; 0047-0049, (2021/11/10)
The invention discloses an industrial production method of a tebuthiuron active compound. The method comprises the following steps: (1) dissolving a raw material 2-methylamino-5-tertbutyl-1, 3, 4-thiadiazole in an inert solvent to prepare an inert solvent solution with a certain concentration; (2) carrying out a photochemical reaction on the 2-methylamino-5-tertbutyl-1, 3, 4-thiadiazole toluene solution and phosgene or a diphosgene or triphosgene solution; (3) removing phosgene from the material after the photochemical reaction is finished; (4) carrying out amidation reaction on the phosgene-removed material and monomethylamine gas; and (5) after the amidation reaction is finished, carrying out post-treatment on the material to obtain the tebuthiuron product. The product quality is more stable. The device investment is reduced, the device production capacity is improved, the technological process is simpler, and continuous self-control operation of the device is facilitated.
