Ribavirin is a nucleoside analogue biochemical supplied at a minimum purity of 90 %, with CAS number 36791-04-5 and empirical formula C₈H₁₂N₄O₅. Its molar mass is 244,2 g/mol, enabling accurate preparation of solutions and reference materials for laboratory studies. The product is Ribavirin is of interest in antimicrobial and antiviral research contexts as well as broader investigations of nucleoside chemistry and biochemical pathways. It is available from manufacturer Carl ROTH as part of the biochemicals and antimicrobials offering for scientific laboratories. Defined CAS identity and molecular formula support documentation, inventory management and method transfer between sites. The larger unit quantity reduces the need for frequent reordering while remaining practical for controlled laboratory handling. Researchers can integrate this material into assay development, comparative studies and synthetic work that require a consistent nucleoside analogue feedstock.
