C4H4N2O3

C4H4N2O3 is the molecular formula used to describe a set of distinct chemical species that share the same elemental composition. There is no single widely recognized compound exclusively associated with this exact formula. The formula corresponds to a molar mass of approximately 128.09 g/mol.

The formula has four degrees of unsaturation, indicating that its structures would involve rings and/or multiple bonds. With four carbon atoms, two nitrogens and three oxygens, potential motifs include heterocyclic frameworks containing two nitrogen atoms and carbonyl or other oxidized functionalities, such as imide- or lactam-type cores, or oxazolidinone-like arrangements, among other isomeric possibilities. The precise arrangement of atoms determines the compound’s properties and name.

In chemistry databases, C4H4N2O3 may appear as the molecular or empirical formula for novel compounds, reaction intermediates, or theoretical species. In practice, identifying a specific substance requires spectroscopic data (infrared and nuclear magnetic resonance) and, frequently, crystallography to establish an exact structure.

Safety and handling depend on the specific substance corresponding to the formula; generic chemical-handling precautions apply until the material’s identity is confirmed. When a particular isomer or compound with this formula is studied or synthesized, it is given a proper IUPAC name and associated material data sheet with detailed hazard information.
