Spectral and ionization constant studies of substituted 2-hydroxypyridines(1,2-dihydro-2-oxopyridines) was written by Spinner, E.;White, J. C. B.. And the article was included in Journal of the Chemical Society [Section] B: Physical Organic in 1966.HPLC of Formula: 13472-81-6 This article mentions the following:
The uv and ir spectra and the ionization constants of the title compounds containing substituents (3-, 4-, 5-, and 6-Me; 3- and 5-Cl; 3,5-Cl2; 3- and 5-Br; 3,5-Br2; 5-I; 3,5-I2; 3- and 6-OH; 3- and 6-O–; 3- and 5-NO2) have been determined For all the compounds examined the pyridone form predominates. A number of the corresponding 2-methoxypyridines were also studied for reference. 34 references. In the experiment, the researchers used many compounds, for example, 3,5-Dibromo-2-hydroxypyridine (cas: 13472-81-6HPLC of Formula: 13472-81-6).
3,5-Dibromo-2-hydroxypyridine (cas: 13472-81-6) belongs to pyridine derivatives. Pyridine’s the lone pair does not contribute to the aromatic system but importantly influences the chemical properties of pyridine, as it easily supports bond formation via an electrophilic attack. One of the examples of pyridines is the well-known alkaloid lithoprimidine, which is an A3 adenosine receptor antagonist and N,N-dimethylaminopyridine (DMAP) analog, commonly used in organic synthesis.HPLC of Formula: 13472-81-6
