N,N-dimethyl-2,4,5-trichlorobenzenesulfonamide, also known as sulfometuron methyl, is a widely used herbicide belonging to the sulfonylurea class. It is a white crystalline solid with the chemical formula C10H12Cl3N2O2S. N,N-dimethyl-2,4,5-trichlorobenzenesulfonamide is effective in controlling various broadleaf and grassy weeds in agricultural fields, particularly in crops like corn, sorghum, and soybeans. It works by inhibiting the enzyme acetohydroxyacid synthase, which is essential for plant growth, thus preventing the synthesis of essential amino acids and ultimately leading to the death of the weed. Due to its effectiveness and low use rates, sulfometuron methyl is a popular choice among farmers. However, it is important to follow proper application guidelines and precautions to minimize potential environmental and health risks.

4821-31-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4821-31-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,2 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4821-31:
(6*4)+(5*8)+(4*2)+(3*1)+(2*3)+(1*1)=82
82 % 10 = 2
So 4821-31-2 is a valid CAS Registry Number.

An approach to C-N activation: Coupling of arenesulfonyl hydrazides and arenesulfonyl chlorides with: Tert -amines via a metal-, oxidant- and halogen-free anodic oxidation

Sheykhan,Khani,Abbasnia,Shaabanzadeh,Joafshan

, p. 5940 - 5948 (2017)

tert-Amines were harnessed to afford arenesulfonyl hydrazides and arenesulfonyl chlorides via a metal-, oxidant- and halogen-free electrochemical oxidative coupling in an undivided cell at RT. This environmentally benign approach afforded a wide spectrum of sulfonamides in satisfactory yields using cheap and renewable Pencil Graphite Electrodes (PGEs).
