CAS 1131-61-9: Pyridine, 4-phenyl-, 1-oxide

Description: Pyridine, 4-phenyl-, 1-oxide, also known as 4-phenylpyridine N-oxide, is an organic compound characterized by a pyridine ring substituted with a phenyl group and an oxide functional group. Its molecular structure features a nitrogen atom within the six-membered aromatic ring, contributing to its basicity and potential for coordination with metal ions. This compound typically appears as a colorless to pale yellow liquid or solid, depending on its form and purity. It is soluble in organic solvents, reflecting its aromatic nature. Pyridine derivatives, including this compound, are known for their applications in organic synthesis, serving as intermediates in the production of pharmaceuticals, agrochemicals, and dyes. The presence of the N-oxide group can enhance its reactivity, making it useful in various chemical reactions, including oxidation processes. Additionally, it may exhibit biological activity, which can be of interest in medicinal chemistry. As with many nitrogen-containing heterocycles, safety precautions should be taken when handling this compound due to potential toxicity and irritant properties.
