Cytosine is an important intermediate in fine chemicals, pesticides and pharmaceuticals, and has a wide range of applications. In the field of pesticides, a new cytosine peptide-type antibiotic was discovered for the first time. It is a broad-spectrum agricultural antibiotic with high efficiency, low toxicity and low residue. In the field of medicine, cytosine is a nucleic acid substance that can be used as an antiviral drug. It is mainly used to synthesize anti-AIDS drugs and anti-hepatitis B drug lamivudine, anti-cancer drugs gemcitabine, and 5-flucytosine Pyrimidine etc.
