C4H6N2

C4H6N2 is the molecular formula for a set of organic compounds that contain four carbon atoms, six hydrogen atoms, and two nitrogen atoms. The formula by itself does not identify a single molecule; numerous structural isomers share this composition.

Isomerism and representative structures: The two nitrogen atoms can be arranged in different frameworks, leading to distinct constitutional isomers and tautomers. A well-known family in this formula class are the dihydro derivatives of the six-membered heterocycle pyridazine, such as 1,2-dihydropyridazine, 1,4-dihydropyridazine, and 2,3-dihydropyridazine. These are partially saturated rings in which two hydrogens have been added relative to the fully unsaturated parent. Other possible arrangements include acyclic or less conventional ring systems in which the nitrogens are incorporated as amino or imine functionalities on a four-carbon skeleton. The exact structure determines properties and reactivity, making the specific identity of C4H6N2 highly dependent on context.

Properties: The approximate molecular weight of C4H6N2 is 82.1 g/mol. Physical properties such as boiling point, density, and stability vary widely among individual isomers, so a single set of characteristics cannot describe all compounds sharing the formula.

Occurrence and use: C4H6N2 is not a single widely used compound but a formula appearing in chemical databases for several possible isomers, including hypothetical and synthetically explored nitrogen-containing heterocycles. Some isomers may be studied as intermediates in organic synthesis or in theoretical investigations of heterocyclic chemistry.

Safety: Safety and handling depend on the specific structure; consult the material safety data for the exact compound.
