1-Ethyl-4-(trifluoromethylsulfonyl)benzene is an organic compound with the molecular formula C9H9F3SO2. It is a colorless liquid that is soluble in organic solvents. This chemical is characterized by a benzene ring with an ethyl group attached to the first carbon and a trifluoromethylsulfonyl group attached to the fourth carbon. The trifluoromethylsulfonyl group is a significant feature, as it provides the molecule with unique reactivity and stability. 1-ethyl-4-(trifluoromethylsulfonyl)benzene is used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals, particularly in the preparation of sulfonylurea derivatives, which are known for their herbicidal properties. The presence of the trifluoromethyl group enhances the lipophilicity and metabolic stability of the final products, making it a valuable building block in the chemical industry.

Check Digit Verification of cas no

The CAS Registry Mumber 432-85-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,3 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 432-85:
(5*4)+(4*3)+(3*2)+(2*8)+(1*5)=59
59 % 10 = 9
So 432-85-9 is a valid CAS Registry Number.
