C5H6N2

C5H6N2 is a molecular formula representing a class of organic compounds that contain five carbon atoms, six hydrogen atoms, and two nitrogen atoms. It does not describe a single specific molecule; multiple structural isomers conform to this formula. The approximate molecular weight is 94.12 g/mol. The formula has a degrees of unsaturation of four, indicating combinations of rings and multiple bonds in plausible structures.

Possible structural themes include five-membered heterocycles with two nitrogens (such as imidazole- or pyrazole-like cores) bearing carbon-based substituents, as well as acyclic arrangements featuring imine and amine functionalities. In practice, C5H6N2 can correspond to a variety of isomers with different reactivities, stabilities, and physical properties. Consequently, there is no single standard set of properties for the formula.

Analytical characterization relies on spectroscopic methods: nuclear magnetic resonance (NMR), infrared (IR) spectroscopy, and mass spectrometry (MS) help distinguish isomers, often complemented by X-ray crystallography when solid samples are available.

In chemical research, C5H6N2 functions as a generic formula used in databases and during synthetic planning to catalog candidate structures that fit a given molecular formula. Safety and handling depend on the specific isomer; as with other organic compounds, appropriate laboratory practices should be observed.
