Description
Thifensulfuron methyl is a selective postemergence herbicide that belongs to the sulfonamide class of compounds. It is a white crystalline solid with the chemical formula C15H16N6O6S. Thifensulfuron methyl works by inhibiting the acetolactate synthase enzyme in plants, which is essential for the synthesis of branched-chain amino acids. This leads to the cessation of plant growth and eventually death.
Uses
Used in Agriculture:
Thifensulfuron methyl is used as a herbicide for controlling a wide range of broad-leaved weeds and wild garlic in various crops. It is particularly effective in barley and spring wheat fields, where it helps to protect these crops from being overtaken by unwanted plants that compete for nutrients, water, and sunlight.
Used in Barley Fields:
Thifensulfuron methyl is used as a postemergence herbicide in barley fields to control broad-leaved weeds and wild garlic. Its selective nature ensures that it effectively targets the weeds without causing harm to the barley crop.
Used in Spring Wheat Fields:
Similarly, in spring wheat fields, Thifensulfuron methyl is used as a postemergence herbicide to manage broad-leaved weeds and wild garlic. This helps to maintain the health and productivity of the wheat crop by reducing competition from unwanted plants.

Environmental Fate
Chemical/Physical. May hydrolyze in aqueous solutions forming methyl alcohol and

thiophenecarboxylic acid.
Metabolic pathway
The hydrolytic degradation of thifensulfuron methyl is
pH dependent and, in alkaline condition, specifically
yields the corresponding free acid. Primary
degradation cleaves the sulfonylurea moiety to give
two typical hydrolyzed products, sulfonamide and
aminotriazine analogs, derived from thifensulfuron
methyl in acidic and neutral conditions. Hydrolysis of
the ester linkage proceeds in mammals, plants, soils, and also chemical hydrolysis, and opening of the
triazine ring occurs to yield the acetyltriuret analog
identified. On the other hand, by hydrolysis, O-
demethylated thifensulfuron methyl undergoes opening
of the triazine ring to give the corresponding
acetyltriuret analog. Under photolytic conditions,
methyl 3-(4-methoxy-6-methyl-1,3,5-triazin-2-
yl)aminothiophene-2-carboxylate is identified.
Check Digit Verification of cas no
The CAS Registry Mumber 79277-27-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,2,7 and 7 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 79277-27:
(7*7)+(6*9)+(5*2)+(4*7)+(3*7)+(2*2)+(1*7)=173
173 % 10 = 3
So 79277-27-3 is a valid CAS Registry Number.

, (2008/06/13)
The utilization of a positive selection seed screening process to isolate rate variants with resistance to a herbicide is described. The ability to screen large numbers of mutagenized seed has made it feasible to pursue and isolate plants with low frequency dominant herbicide-resistance mutations. The dominant herbicide resistance mutations are useful for many applications including expanding the utility of sulfonylurea herbicides for soybean weed control, production of F1 and F2 seeds, and as selectable markers for efficient seed purification.
