  • Applications

    Artemisin (CAS 481-05-0) is primarily used in the pharmaceutical sector as the active ingredient in artemisinin-based combination therapies (ACTs) for malaria treatment. Beyond its role as a therapeutic active ingredient, it is commonly treated as a starting material or intermediate in organic synthesis to prepare artemisinin-derived compounds and other pharmacologically active derivatives, supporting medicinal chemistry and drug discovery efforts. It is also regarded as a natural-product–based scaffold to guide synthesis routes in the development of new medicines. In addition, artemisin may be considered in pharmaceutical manufacturing research and supply chains based on natural sources, subject to local regulations.
