Wijnberger, C.; Habraken, Clarisse L. published an article about the compound: 1H-Pyrazole-5-carbaldehyde( cas:948552-36-1,SMILESS:O=CC1=CC=NN1 ).Electric Literature of C4H4N2O. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:948552-36-1) through the article.
Uv and 1H N.M.R. spectral data and C : O frequencies of some methylpyrazoles containing in the 3-, 4- or 5-position, a formyl-, acetyl- or ethoxycarbonyl group are reported. These data confirm earlier conclusions that, in particular, the 4-pyrazolyl group acts as an electron releasing group. The syntheses of a number of formyl-, acetyl- and ethoxycarbonyl pyrazoles are described. In addition, some 4-dicyanovinyl- and 4-tricvanovinylpyrazoles were investigated.
The article 《Pyrazoles. VI. Electron-releasing capacity of the pyrazole ring》 also mentions many details about this compound(948552-36-1)Electric Literature of C4H4N2O, you can pay attention to it, because details determine success or failure
