  • Applications

    Junosine (CAS 103956-34-9) is typically used as a nucleoside-building block in pharmaceutical research and development. It may serve as an intermediate in the synthesis of nucleoside analogs for antiviral and anticancer drug discovery and as a research reagent in nucleoside chemistry. In biochemical and molecular biology contexts, it can act as a substrate or reference compound in enzyme assays and polymerase studies. It is employed in analytical method development and quality control for nucleosides and derivatives, and is commonly used in academic and industrial laboratories as a general reagent for exploratory synthesis and method validation. Usage is subject to local regulations and formulation limits.
