Application of 27828-71-3. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 5-Hydroxynicotinic acid, is researched, Molecular C6H5NO3, CAS is 27828-71-3, about Chemical constituents in n-butanol extracts of Cheanomeles speciosa (Sweet) Nakai.

Chem. constituents in n-butanol extracts of Chaenomeles speciosa were investigated. Multi-chromatog. methods including Silicagel column chromatog. and Sephadex LH-20 gel permeation were employed for the isolation and purification The structures were identified on the basis of chem. evidence and spectral data. Eight compounds were isolated and identified as 1,2,4-Benzenetriol (1), gallic acid (2), epi-quinide (3), 5-Hydroxynicotinic acid (4), p-coumaric acids glucosyl esters (5), p-hydroxybenzoic acid glucoside (6), (6S,9R)-roseoside (7) and Vomifolioll-O-β-D-xylopyranosy-6-O-β-D-glucopyranoside (8). Compounds 1-6 were obtained from this genus for the first time.
This compound(5-Hydroxynicotinic acid)Application of 27828-71-3 was discussed at the molecular level, the effects of temperature and reaction time on the properties of the compound were discussed, and the optimum reaction conditions were selected.
