Application:
Guanine (CAS 73-40-5) can be used for biochemical studies; can be used as the intermediates of the antiviral drugs Acyclovir; can be used as the intermediate of thioguanine and open-ringed guanine. Guanine is one of the four main nucleobases found in the nucleic acids DNA and RNA.Guanine is a purine derivative, consisting of a fused pyrimidine-imidazole ring system with conjugated double bonds. Guanine is an important base composition of nucleic acids, being one of the four major bases of DNA and RNA as well as the compassion of various kinds of guanylate. Its N9 can be connected with the C1 of ribose or deoxyribose with β-glycosidic bond to obtain guanosine or deoxy-guanosine.
