Description
Cyclosulfamuron is a herbicide that was launched in 1997 by American Cyanamid and is now marketed by BASF. It is used for controlling a wide range of broadleaf weeds and sedge species in various crops, including rice, wheat, and barley. Cyclosulfamuron is known for its effectiveness and selectivity in controlling weeds without causing significant harm to the crops.
Uses
Used in Agricultural Industry:
Cyclosulfamuron is used as a herbicide for controlling a wide range of broadleaf weeds and sedge species in rice, wheat, and barley crops. It is effective in controlling weeds such as Cyperus serotinus, C. difformis, Elatine triandra, Eleocharis congesta, E. kuroguwai, Lindernia annua, L. procumbens, M. vaginalis, Rotala indica, Sagittaria pygmaea, S. trifolia, and Scirpus juncoides. The selectivity in the rice paddy is achieved due to factors like rapid metabolic degradation of the herbicide in rice shoots, placement of rice seedlings during transplanting, and the compound's soil-binding properties, which retain cyclosulfamuron in the upper soil layer of the paddy.
Used in Analytical Studies:
Cyclosulfamuron is also used in the analytical study of the importance of optimizing chromatographic conditions and mass spectrometric parameters for supercritical fluid chromatography/mass spectrometry. This application helps in understanding the behavior of the herbicide in various environments and its interaction with other compounds.
Trade Names and Combinations:
In rice, cyclosulfamuron is commercialized under the trade names "Ichiyonmaru" and "Saviour." It is available in combinations with other herbicides such as daimuron and cafenstrole (sold as "Nebiros"), pentoxazone (sold as "Utopia"), esprocarb (sold as "Shakariki"), and pretilachlor (sold as "Kanetsugu‐Radical," introduced in Japan in 2015).
Synthesis:
Cyclosulfamuron cannot be synthesized by any of the general methods depicted in Scheme 2.2.1. The synthesis of cyclosulfamuron and its intermediate products was reported in the patent literature by Brady et al. and Tan et al. Brady et al. described a straightforward reaction of 2-amino-4,6-dimethoxypyrimidine with chlorosulfonylisocyanate (CSI) at 0 °C with a mixture of 2-aminophenyl cyclopropyl ketone and triethylamine to yield 70% of the desired herbicide.
Check Digit Verification of cas no
The CAS Registry Mumber 136849-15-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,8,4 and 9 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 136849-15:
(8*1)+(7*3)+(6*6)+(5*8)+(4*4)+(3*9)+(2*1)+(1*5)=155
155 % 10 = 5
So 136849-15-5 is a valid CAS Registry Number.

Method for producing a solid herbicide formulation
-
, (2008/06/13)
The invention relates to a method for producing a solid herbicide formulation containing a) a herbicide from the group of sulfonylurea, or the salts thereof which are useful in the agricultural domain, b) optionally at least one other herbicide, c) optionally a safener, and d) at least one formulation adjuvant. A suspension is formed in water, consisting of the sulfonylurea a), optionally at least one other herbicide b), optionally a safener c) and at least one formulation adjuvant d). The suspension is adjusted to a pH value between 6.5 and 8 by adding an acid or a base, and is then dried to obtain the solid formulation.
