Ultraviolet absorption spectra and dipole moments of substituted pyridines. IV. Aminopyridinecarboxylate esters was written by Gandolfo, Concetta;Buemi, Giuseppe;Favini, Giorgio. And the article was included in Gazzetta Chimica Italiana in 1971.Category: esters-buliding-blocks This article mentions the following:
Calculated electron transition energies and dipole moments are in good agreement with exptl. values for Me amino nicotinates, Me amino picolinates, and Me amino isonicotinates. The preferred conformation of the CO2Me group is Am for the nicotinates, Bo for the picolinates, and Ap or Bp for the isonicotinates. The Am conformation is favored in nicotinates when the NH2 group is ortho or meta with respect to CO2Me. In the experiment, the researchers used many compounds, for example, Methyl 2-aminonicotinate (cas: 14667-47-1Category: esters-buliding-blocks).
Methyl 2-aminonicotinate (cas: 14667-47-1) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Category: esters-buliding-blocks
