C5H4N4O3

C5H4N4O3 is a chemical formula that denotes a molecule containing five carbon atoms, four hydrogen atoms, four nitrogen atoms, and three oxygen atoms. Its nominal molar mass is about 168.12 g/mol. The formula presents six degrees of unsaturation, indicating the presence of rings and multiple bonds in potential structures.

Because several constitutional isomers can share this formula, the exact properties of a compound with C5H4N4O3 depend on its specific structure. Without a defined arrangement of atoms, characteristics such as melting point, solubility, and reactivity cannot be uniquely determined. In heterocyclic chemistry, plausible structural motifs for molecules with this formula include nitrogen-rich rings such as tetrazole or imide-like frameworks, among other possible arrangements of carbon, nitrogen, and oxygen atoms.

Identification of a C5H4N4O3 compound relies on spectroscopic data and analytical techniques. Nuclear magnetic resonance (NMR), infrared spectroscopy (IR), and mass spectrometry (MS) help determine functional groups and connectivity, while X-ray crystallography can reveal precise three-dimensional structure when crystals are available. Once the exact structure is known, standard chemical property data (solubility, stability, and reactivity) can be ascertained.

Potential applications and implications vary by isomer. Molecules with nitrogen-rich rings are of interest in medicinal chemistry as scaffolds or intermediates in synthesis. Some structural classes with high nitrogen content can exhibit energetic or explosive characteristics, underscoring the importance of appropriate safety practices and containment when handling such compounds.
