C5H4N2O4

C5H4N2O4 is the chemical formula for 5-nitrouracil. Uracil is a pyrimidine base, one of the fundamental building blocks of nucleic acids. In 5-nitrouracil, a nitro group (NO2) is substituted at the fifth position of the uracil ring. This modification alters the electronic and physical properties of the uracil molecule.

5-nitrouracil is a synthetic compound and is not found naturally in biological systems. Its synthesis typically involves the nitration of uracil. The presence of the nitro group makes the molecule more electron-deficient compared to uracil itself. This can affect its reactivity in various chemical reactions.

In the field of chemistry, 5-nitrouracil has been explored for its potential as a chemical intermediate or as a component in the synthesis of more complex molecules. Research has also investigated its biological activity, although its direct use as a therapeutic agent is not widespread. Its structural similarity to uracil suggests potential interactions with biological pathways related to nucleic acid metabolism or enzyme inhibition, but this is an area of ongoing scientific study. The compound's stability and reactivity are key factors considered in its handling and application in laboratory settings.
