Description
Mesosulfuron-methyl is a sulfonylurea herbicide specifically designed for the control of grass weeds in cereal crops. It was introduced by Bayer CropScience in 2001 and is known for its broad-spectrum post-emergence control capabilities. Mesosulfuron-methyl works primarily through the leaves of treated weeds, but can also be absorbed by the soil and roots of highly susceptible grasses.
Used in Agricultural Industry:
Mesosulfuron-methyl is used as a herbicide for the control of grass weeds in cereal crops, such as soft and durum wheat, triticale, and rye. It is effective against 24 different grass weed species from 12 different families, including commercially important species like Agrostis spp., A. myosuroides, A. spica-venti, Avena spp., Lolium spp., P. brachystachys, P. minor, P. paradoxa, P. annua, P. trivialis, Pucciniella spp., and Sclerochloa kengiana. Additionally, it controls or suppresses persistent grass weed species like Bromus catharticus, B. diandrus, B. erectus, B. japonicus, B. mollis, B. tectorum, B. secalinus, B. sterilis, and Vulpia spp.
Mesosulfuron-methyl is often used in combination with other active ingredients and safeners, such as mefenpyr-diethyl, to enhance its effectiveness and selectivity. Some of the straight products and combinations include "Atlantis OF," "Silverado," "Osprey," "Atlantis WG," "Cossack," and "Pacifica," which are formulated with iodosulfuron methylsodium, diflufenican, and propoxycarbazone sodium.
The safener mefenpyr diethyl, along with iodosulfuron methyl sodium, selectively accelerates the degradation of the active ingredient in cereals, turning it into non-phytotoxic compounds, thus providing protection to the crops while still effectively controlling weeds.
Check Digit Verification of cas no
The CAS Registry Mumber 208465-21-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,8,4,6 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 208465-21:
(8*2)+(7*0)+(6*8)+(5*4)+(4*6)+(3*5)+(2*2)+(1*1)=128
128 % 10 = 8
So 208465-21-8 is a valid CAS Registry Number.

Preparation method of mesosulfuron-methyl
-
, (2019/06/30)
The invention relates to a preparation method of mesosulfuron-methyl. The method comprises the following steps: taking 4-cyano-2-nitrobenzoate as a starting raw material; firstly performing a nucleophilic substitution reaction with benzyl mercaptan; then, performing reduction hydrogenation by using raney nickel, performing methylsulfonyl acidylation by using methylsulfonyl chloride; then, performing chlorination by using chlorine gas and performing ammoniation by using ammonia gas to obtain a key intermediate, namely 2-methoxycarbonyl-5-methanesulfonyl ammonia toluenesulfonamide; and finally,performing condensation to obtain a target product, namely the mesosulfuron-methyl. A route of the method is mild in reaction process condition; the operation is easy; the method is suitable for industrial mass production; less environmental pollution is caused; and the method is a relatively good novel method for synthesizing the mesosulfuron-methyl.
