About Parthenolide

Parthenolide is an API reference standard carrying the CAS registry number 20554-84-1. Its molecular formula is C15H20O3 and its molecular weight is 248.32 g/mol. Its systematic (IUPAC) name is (1S,2S,4R,7E,11S)-4,8-dimethyl-12-methylidene-3,14-dioxatricyclo[9.3.0.02,4]tetradec-7-en-13-one.

It is supplied as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

As a reference sample of the parent drug substance, it is used for identification, assay and impurity-profiling work during analytical method development, validation (AMV) and routine QC. It is used across pharmaceutical manufacturing and academic and industrial research.

Vaqora Chemicals supplies Parthenolide in 10 mg, 25 mg, 50 mg and 100 mg packs, each shipped with a Certificate of Analysis (COA), and exports worldwide.
