C4H3ClN2

C4H3ClN2 is the molecular formula for several chemical compounds, the most notable of which is 4-chloropyrimidine. This compound is a derivative of pyrimidine, a heterocyclic aromatic organic compound similar to benzene but with two nitrogen atoms at positions 1 and 3 of the six-membered ring. In 4-chloropyrimidine, a chlorine atom is substituted at the fourth position of the pyrimidine ring.

4-chloropyrimidine is a solid at room temperature and possesses a distinct odor. It is typically synthesized through various chemical reactions, often involving pyrimidine precursors. Its chemical properties are influenced by the presence of both the electronegative chlorine atom and the electron-withdrawing nitrogen atoms within the aromatic ring. This makes it reactive in certain organic synthesis pathways.

As a chemical intermediate, 4-chloropyrimidine finds applications in the synthesis of pharmaceuticals, agrochemicals, and other specialty organic compounds. The chlorine atom can be readily displaced by nucleophiles, allowing for the introduction of various functional groups onto the pyrimidine core. This reactivity is key to its utility in building more complex molecular structures. Research into its properties and applications continues in various fields of organic chemistry and medicinal chemistry. Other isomers with the formula C4H3ClN2 also exist, but 4-chloropyrimidine is the most commonly referenced.
