Artemisinin CAS 63968-64-9
Artemisinin (qinghaosu, CAS 63968-64-9) is a white to off-white crystalline powder extracted from sweet wormwood (Artemisia annua L.), not made by synthesis. It is the active ingredient in artemisinin-based antimalarial drugs and the starting material for DHA, artesunate and artemether in WHO-recommended ACT therapies. UATChem supplies pharmacopoeia-grade material at 98.5% min (HPLC) in 1 kg aluminium foil bags for trials and 25 kg fibre drums for production, with COA, HPLC trace and export documents on every order.

The Antimalarial API
Artemisinin is a sesquiterpene lactone found in the plant Artemisia annua, isolated by solvent extraction, purified and repeatedly recrystallized. The unusual feature is a strained peroxide bridge inside the molecule: it reacts with parasite iron and clears Plasmodium falciparum quickly, including multi-drug resistant strains. The same bridge is heat- and light-sensitive, which is why storage rules matter as much as assay. UATChem supplies pharmacopoeia-grade material, not a technical extract.
Where the API Goes
- Antimalarial drug production. Active ingredient in artemisinin-based tablets and capsules for uncomplicated P. falciparum and P. vivax malaria, and a core component of artemisinin combination therapy (ACT) regimens.
- Derivative synthesis. The universal starting material for dihydroartemisinin (DHA), artesunate, artemether and arteether, the active molecules behind all WHO-recommended first-line ACT formulations.
- Pharmaceutical R&D and reference standards. Characterized 98.5% lots serve as reference material in antimalarial development and QC; in oral solid work it is commonly co-formulated with Povidone (PVP) CAS 9003-39-8 to improve dissolution and tablet processability.
- New indication research. Active in preclinical studies for anti-inflammatory, anti-parasitic and oncology directions, built on its broad biological profile and low mammalian toxicity.

FAQ
Q: Is the artemisinin plant-extracted?
A: Yes. Extracted from Artemisia annua, purified and recrystallized to pharmacopoeia grade.
Q: Which derivatives is it used to make?
A: DHA first, then artesunate, artemether and arteether for WHO ACT regimens.
Q: What assay and standard apply?
A: 98.5% min by HPLC, melting 150-153 C, specific rotation +75 to +78 degrees.
Q: What is the minimum trial order?
A: 1 kg in an aluminium foil bag; production runs start at 25 kg fibre drums.
Q: How should artemisinin be stored?
A: Below 25 C, sealed and light-protected, to preserve the peroxide bridge for 24 months.
