It is a derivative of benzoic acid, featuring a nitro group at the 3-position, a trifluoromethylsulfonyl group at the 4-position, and a carboxylic acid group. <4-Carboxy-3-nitro-phenyl>-trifluormethyl-sulfon is often used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals due to its reactive functional groups, which can be further modified to form a range of different molecules. The trifluoromethylsulfonyl group, in particular, is known for its reactivity and stability, making it a valuable component in the creation of complex organic molecules.
The CAS Registry Mumber 1933-61-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,3 and 3 respectively; the second part has 2 digits, 6 and 1 respectively. Calculate Digit Verification of CAS Registry Number 1933-61: (6*1)+(5*9)+(4*3)+(3*3)+(2*6)+(1*1)=85 85 % 10 = 5 So 1933-61-5 is a valid CAS Registry Number.
