C8H8N2O2

C8H8N2O2 is a molecular formula that describes a set of chemical compounds rather than a single substance. It comprises eight carbon atoms, eight hydrogen atoms, two nitrogen atoms, and two oxygen atoms. With a hydrogen deficiency (DBE) of six, there are multiple possible constitutional isomers that fit this formula, so C8H8N2O2 typically refers to a family of related structures rather than one specific compound.

Structural possibilities for isomers with this formula commonly involve aromatic or heteroaromatic cores that incorporate two nitrogens and one or more carbonyl-containing groups. Motifs such as amide or imide functionalities, or fused ring systems that satisfy the formula, are among the plausible arrangements. The exact physical and chemical properties—melting point, boiling point, solubility, reactivity—vary significantly between individual isomers.

Identification and characterization of a specific compound require structural information beyond the formula. Chemists use representations such as SMILES or InChI, together with spectroscopic data (nuclear magnetic resonance, infrared spectroscopy, mass spectrometry) and, when possible, crystallographic data, to confirm a particular isomer.

Applications and occurrence are diverse because these formulae arise in various synthetic contexts. Isomers with this formula may serve as laboratory intermediates in organic synthesis, and some could appear in pharmaceutical, dye, or agrochemical research, depending on their exact structure.

Safety and handling depend on the specific isomer. Because properties and hazards differ among isomers, the safety data sheet for the exact compound should be consulted. For reference, a catalog or database entry (for example, a CAS number or chemical name) is needed to identify a particular C8H8N2O2 isomer.
