artemisinin Imp-A

Artemisinin Imp-A is a synthetic byproduct derived from the partial oxidation of the 1,2,4-trioxane core in artemisinin, resulting in a hydroxylated derivative at the C-10 position. This compound retains the sesquiterpene lactone scaffold but exhibits altered oxygenation patterns, including a cleaved peroxide bridge and an additional hydroxyl group. Its structural similarity to artemisinin enables its use as an HPLC reference standard for monitoring synthetic pathway purity in antimalarial drug production.
