2-Hydroxypyridine

CAS: 142-08-5

2-Hydroxypyridine is a heterocyclic organic compound that contains a nitrogen atom and two hydrogen atoms. It is a proton donor and has been shown to be an effective inhibitor of HIV infection. 2-Hydroxypyridine also inhibits bacterial growth by inhibiting the synthesis of DNA and RNA, which prevents protein synthesis and cell division. The intramolecular hydrogen bonds in protonated 2-hydroxypyridine form tautomers that can change from one form to another, with the equilibrium depending on pH. 2-Hydroxypyridine is a natural compound found in picolinic acid or in plants such as parsley, black pepper, or cinnamon. X-ray crystal structures of 2-hydroxypyridine have revealed that it has a planar geometry with an intramolecular hydrogen bond between the nitrogen atom and the protonated carbon atom. This bond causes significant kinetic energy to be released during the reaction mechanism, which may
