5-Formyl-1-methyl-1H-pyrrole-2-carbonitrile (cas: 81698-03-5) belongs to nitriles. Nitrile function is a very important functional group because it can be manipulated to other functional groups such as carboxylic acid by hydrolysis or amine by reduction, respectively. Some nitriles are manufactured by heating carboxylic acids with ammonia in the presence of catalysts. This process is used to make nitriles from natural fats and oils, the products being used as softening agents in synthetic rubbers, plastics, and textiles and for making amines.HPLC of Formula: 81698-03-5

EPR studies of 1-methyl-2-substituted-5-pyrrolylcarbonyl fluorinated nitroxides and dual-parameter correlation analysis of their hyperfine splitting constants was written by He, Roderick Hai-Ying;Zhao, Cheng-Xue;Zhou, Cheng-Ming;Jiang, Xi-Kui. And the article was included in Tetrahedron in 1999.HPLC of Formula: 81698-03-5 The following contents are mentioned in the article:

Three series of new 1-methyl-2-substituted-5-pyrrolylcarbonyl fluorinated nitroxides, (I;Rf = C2F5, n-C3F7, n-C7F15; R=H,Me,Cl,CN,COMe,NO2,SMe,CO2Me,SiMe3,Br,OMe), generated by the H-abstraction/spin-trapping reaction of eleven 1-methyl-2-substituted-pyrrole-5-carbaldehydes (6) with the H-abstracting agent [RfN(O·)Rf] 1 and the spin-trapping agent RfNO 2, were studied by ESR. Correlation anal. of their aN values with polar and spin-delocalization substituent constants shows that aN values are mainly affected by the polar effect of the 2-substituent, but the spin-delocalization effect also exists. This study involved multiple reactions and reactants, such as 5-Formyl-1-methyl-1H-pyrrole-2-carbonitrile (cas: 81698-03-5HPLC of Formula: 81698-03-5).
