2cyano5nitropyridine

2-Cyano-5-nitropyridine is an organic compound with the chemical formula C6H3N3O2. It is a derivative of pyridine, a heterocyclic aromatic organic compound. The molecule features a cyano group (-CN) at the 2-position and a nitro group (-NO2) at the 5-position of the pyridine ring. This specific arrangement of functional groups imparts distinct chemical properties to the molecule.

The compound typically appears as a solid, often crystalline, and its color can range from yellow to orange depending on its purity. Its solubility characteristics are influenced by the polar nitro and cyano groups, generally exhibiting some solubility in polar organic solvents.

2-Cyano-5-nitropyridine serves as a valuable intermediate in organic synthesis. The presence of both an electron-withdrawing nitro group and a cyano group makes the pyridine ring susceptible to nucleophilic aromatic substitution reactions, particularly at positions ortho and para to these substituents. This reactivity allows for the introduction of various other functional groups, leading to the synthesis of more complex pyridine derivatives. These derivatives find applications in the development of pharmaceuticals, agrochemicals, and materials science. Its precise role in synthesis often involves reactions that modify or replace the cyano or nitro groups, or that occur on the pyridine ring itself due to their activating influence.
