2828-42-4 Usage
General Description
PROXIMPHAM, also known as 3-(phenylsulfonyl)-1,1-dimethylurea, is a chemical herbicide commonly used in agriculture to control broadleaf weeds and grasses in various crops such as soybeans, cotton, and peanuts. It works by inhibiting the synthesis of specific enzymes that are essential for plant growth, leading to the disruption of cellular processes and ultimately the death of the unwanted vegetation. Proximpham is considered to have low toxicity to mammals and is relatively stable in the environment. However, it is important to follow safety guidelines and regulations when handling and applying this chemical to minimize potential risks to human health and the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 2828-42-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,2 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2828-42:
(6*2)+(5*8)+(4*2)+(3*8)+(2*4)+(1*2)=94
94 % 10 = 4
So 2828-42-4 is a valid CAS Registry Number.

Reactivity of bis(arylcarbamoyl)-N-arylphenacylamine oximes. Synthesis of 1,3-dihydroimidazol-2-ones and N-unsubstituted O- arylcarbamoylhydroxylamines
Coskun, Necdet
, p. 475 - 484 (2007/10/03)
N-Arylphenacylamine oximes 1 reacted with aryl isocyanates in refluxing benzene to give bis(arylcarbamoyl)-N-arylphenacylamine oximes 2 in good yields. Compounds 2 reacted with equimolar amount of TsOH.H2O in THF at room temperature to give imidazol-2-ones 5 and O-arylcarbamoylhydroxylammonium tosylates 6 in high yields. Compounds 2 were heated under vacuum to induce Beckmann fragmentation but the resulting products were 1,3,4-triaryl-1,3- dihydroimidazol-2-ones 5 instead of the expected 1,3-diazetidinones 4.
