C5H4N2O2

C5H4N2O2 is the molecular formula for several chemical compounds, with the most common being uracil. Uracil is a pyrimidine base that is one of the four bases found in RNA. It pairs with adenine in RNA and plays a crucial role in protein synthesis. Uracil is a white crystalline solid and is soluble in water. It is also a component of the drug 5-fluorouracil, which is used in chemotherapy.

Other compounds with the molecular formula C5H4N2O2 include isocytosine and pseudouridine. Isocytosine is a tautomer of cytosine, another pyrimidine base found in DNA and RNA. Pseudouridine is a modified form of uridine, a nucleoside composed of uracil and ribose. Pseudouridine is found in tRNA and rRNA and is involved in their structure and function. The specific properties and applications of each isomer depend on its unique structure and arrangement of atoms. The study of these isomers is important in understanding various biological processes and developing new pharmaceuticals.
