Description
Rimsulfuron, a N-sulfonylurea herbicide, is characterized by its N-carbamoyl-3-(ethylsulfonyl)pyridine-2-sulfonamide structure, with a 4,6-dimethoxypyrimidin-2-yl group attached at the amino nitrogen atom. It is specifically designed to target and control various types of weeds by inhibiting their growth through the suppression of acetolactate synthase (ALS), a key enzyme in protein synthesis.
Uses
Used in Agricultural Industry:
Rimsulfuron is used as a herbicide for controlling annual broadleaf weeds, certain grasses, and perennial broadleaf weeds. It is particularly effective against glyphosate-resistant weed species, such as marestail or horseweed. By inhibiting the ALS enzyme, Rimsulfuron blocks the synthesis of essential amino acids (isoleucine, leucine, and valine) in plants, thereby disrupting protein synthesis and halting weed growth.
Additionally, Rimsulfuron is registered for use in the United States and Canada as a U.S. EPA restricted Use Pesticide (RUP) for some formulations, and it is also approved for use in select European Union countries. This widespread application highlights its importance in modern agriculture for effective weed management and crop protection.

Metabolic pathway
The primary degradation pathway in most of the
systems examined is the contraction or
rearrangement and hydrolysis of the sulfonylurea
linkage to yield two products that have N-pyridyl-N-
pyrimidyl urea and N-pyridyl-N-pyrimidylamine
moieties, and fragments of pyridine sulfonamide, 4,6-
dimethoxy-2-pyrimidylurea, and 4,6-dimethoxy-2-
amino-pyrimidine, respectively. In plants,
demethylation and hydroxylation reactions follow the contraction or rearrangement to give N-3,4-dihydroxy-
5-methoxy-2-pyrimidyl-N(3-ethylsulfonyl-2-
pyridyl)amine.
Check Digit Verification of cas no
The CAS Registry Mumber 122931-48-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,9,3 and 1 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 122931-48:
(8*1)+(7*2)+(6*2)+(5*9)+(4*3)+(3*1)+(2*4)+(1*8)=110
110 % 10 = 0
So 122931-48-0 is a valid CAS Registry Number.

Synthesis method of rimsulfuron
-
, (2020/09/20)
The invention relates to the technical field of herbicide synthesis, and discloses a rimsulfuron synthesis method, which comprises the following steps of: S1, preparation of raw materials; S2, condensation; and S3, purification: A, adding a rimsulfuron crude product obtained in S2 into a first solvent, heating to 40-100 DEG C, and keeping the temperature for 2-5 hours, wherein the mass ratio of the rimsulfuron crude product to the first solvent is 1: 2; B, adding a second solvent into the liquid treated in the step A, then cooling a liquid system to -10 to 20 DEG C, then filtering precipitates, and taking a filter cake for later use, wherein the mass ratio of the second solvent to the first solvent in the step A is 1: 2; C, adding the filter cake obtained in the step B into a third solvent, stirring and pulping, and keeping the pulping temperature at 0-50 DEG C for 2-6 hours, wherein the mass ratio of the third solvent to the first solvent in the step A is 1: 2.5; and D, filtering anddrying the substance treated in the step C to obtain the rimsulfuron active compound. The purity of the finally prepared rimsulfuron can be improved.
