  • Applications

    Noscapine, CAS 128-62-1, is commonly used in pharmaceuticals as an antitussive in cough medicines; in research and development, it serves as a chemical scaffold and synthetic building block for medicinal chemistry studies of alkaloid derivatives; it is investigated as a tubulin-binding agent with potential anticancer activity in laboratory settings; and it is sometimes employed as a starting material or reference compound in the synthesis of related opium alkaloids.
