Description
SULFENTRAZONE is a synthetic herbicide characterized by its ability to control sedges in turfgrass. It exhibits solubility in water at varying pH levels, with 100 mg/L at pH 6, 800 mg/mL at pH 7, and 1,600 mg/mL at pH 7.5. Additionally, it is soluble to some extent in acetone and other polar organic solvents. SULFENTRAZONE has a pKa value of 6.56 and is considered stable.
Uses
Used in Agriculture:
SULFENTRAZONE is used as a herbicide for controlling sedges in turfgrass. Its application helps maintain the quality and appearance of turfgrass by eliminating unwanted sedges that can compete with the grass for resources and space.
Used in Turfgrass Management:
In the turfgrass industry, SULFENTRAZONE is utilized as a selective herbicide to target and control sedges without causing significant harm to the desired grass species. This selective action allows for effective weed control while preserving the health and integrity of the turfgrass.

Metabolic pathway
When 14C-sulfentrazone is applied to coffee senna
and sicklepod through the roots, 83% of the parent
compound remains in coffee senna leaf tissue after
9 h exposure and in contrast, sicklepod takes up
relatively less sulfentrazone through the root and
metabolizes sulfentrazone in the foliage more rapidly
than coffee senna. The primary detoxification reaction
appears to be oxidation of the methyl group on the
triazolinone ring, resulting in the formation of the more
polar hydroxymethyl derivative. The aniline analog is
identified as a plant-specific metabolite. The tolerance
of sicklepod to sulfentrazone is primarily due to a
relatively high rate of metabolism of sulfentrazone
compared with coffee senna. When 14C-sulfentrazone
is administered orally to rats, goats, and hens in a
daily diet, administered radioactivity is quantitatively
excreted in the urine, feces, or hen excreta. In all of
the species, unchanged sulfentrazone and two non-conjugated metabolites are found, which are 3-hydroxymethyl and carboxylic acid derivatives, the
latter of which decomposes at high temperature or
acidic pH to give the corresponding desmethyl analog
of sulfentrazone. In rats, a minor reduction metabolite
is detected which is tentatively characterized as the
2,3-dihydro-3-hydroxymethyl derivative.
Check Digit Verification of cas no
The CAS Registry Mumber 122836-35-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,8,3 and 6 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 122836-35:
(8*1)+(7*2)+(6*2)+(5*8)+(4*3)+(3*6)+(2*3)+(1*5)=115
115 % 10 = 5
So 122836-35-5 is a valid CAS Registry Number.

Preparation method of sulfonyl carfentrazone-ethyl
-
, (2022/04/03)
The invention relates to a preparation method of sulfonyl carfentrazone-ethyl, which takes 2, 4-dichloroaniline as an initial raw material, and comprises the following steps of: 1, carrying out nitration reaction on a benzene ring of the 2, 4-dichloroaniline; as the N-difluoromethyl substituted triazolinone ring is formed, nitration and reduction reactions on the benzene ring can be carried out before the N-difluoromethyl substituted triazolinone ring is formed, and the N-difluoromethyl substituted triazolinone ring does not need to be placed in reaction environments such as mixed acid nitration and nitro reduction in the presence of concentrated sulfuric acid and concentrated nitric acid, so that the generation of byproducts is reduced, and the synthesis yield of the compound is improved; the production cost of the compound is reduced; and moreover, the problem that an N-difluoromethyl substituted triazolinone ring is unstable under certain nitrification conditions is also avoided, so that the nitrification and reduction methods have more choices, and a more advanced sulfonyl carfentrazone-ethyl production process is favorably developed.
