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