Nucleobases and their Analogs

Nucleobases and their Analogs — includes purine and pyrimidine nitrogen bases and their substituted analogs, such as chlorinated, aza-substituted derivatives, or their salt forms, which serve as the basic building units of nucleic acids. Substituent variations on the heterocyclic ring provide a range of solubility and reactivity properties for further synthesis needs.

Nucleobases and their Analogs are used in the synthesis of modified nucleosides and nucleotides, molecular biology research, and the development of reference compounds for research on purine and pyrimidine metabolic pathways. Analogs such as azauracil or chloropurine derivatives are commonly used as starting materials for heterocyclic substitution reactions to build more complex nucleoside analog structures.
