4-(5-chloro-2-nitro-phenyl)-2-methyl-pyrrole-3-carboxylic acid ethyl ester is a complex organic compound with the chemical formula C13H12ClNO4. It is a derivative of pyrrole, a heterocyclic aromatic organic compound consisting of a five-membered ring with two carbon atoms and two nitrogen atoms. The molecule features a 5-chloro-2-nitro-phenyl group attached to the pyrrole ring, a methyl group at the 2-position, and a carboxylic acid group at the 3-position, which is further esterified with an ethyl group. 4-(5-chloro-2-nitro-phenyl)-2-methyl-pyrrole-3-carboxylic acid ethyl ester is known for its potential applications in the synthesis of pharmaceuticals and agrochemicals, particularly as an intermediate in the production of certain herbicides and other bioactive molecules. Its chemical structure and properties make it a versatile building block in organic synthesis, although its specific uses and safety considerations should be carefully evaluated.
The CAS Registry Mumber 5881-65-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,8 and 1 respectively; the second part has 2 digits, 6 and 5 respectively. Calculate Digit Verification of CAS Registry Number 5881-65: (6*5)+(5*8)+(4*8)+(3*1)+(2*6)+(1*5)=122 122 % 10 = 2 So 5881-65-2 is a valid CAS Registry Number.
