Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya called Structure of β-hydroxy derivatives of monopyridinecarboxylic acids, Author is Grachev, V. T.; Zaitsev, B. E.; Stolyarova, L. G.; Smirnov, L. D.; Dyumaev, K. M., which mentions a compound: 27828-71-3, SMILESS is O=C(O)C1=CN=CC(O)=C1, Molecular C6H5NO3, Product Details of 27828-71-3.
The UV spectra of the pyridinemonocarboxylic acids, their 5-hydroxy derivatives (and the Et esters of these), and 5-butoxypicolinic and 6-butoxynicotinic acid were determined in neutral, acid, and basic media. The IR spectra of some of these [and of 3-hydroxyisonicotinic acid (I) and its Et ester] were also determined (crystalline). The 5-OH analogs underwent ionization at the CO2H group and formed intermol. H bonds; I existed only partially in the ionized state and formed intramol. H bonds.
The article 《Structure of β-hydroxy derivatives of monopyridinecarboxylic acids》 also mentions many details about this compound(27828-71-3)Product Details of 27828-71-3, you can pay attention to it, because details determine success or failure
