4-Hydroxypyridine

CAS: 626-64-2

4-Hydroxypyridine is a nitrite ion that contains two nitrogen atoms. It is used to study microbial metabolism and the role of nitrogen in biological systems. 4-Hydroxypyridine can be synthesized from pyridinium, which can be prepared by treating aniline with nitrous acid. The synthesis of 4-hydroxypyridine has been investigated using a hydroxylation reaction catalyzed by palladium, followed by cyclization to form a cyclic peptide. This reaction has been shown to have significant cytotoxicity against HIV-infected cells, with light emission as a result of the reaction between the hydrogen atom on the pyridine ring and oxygen molecule.
