About Gentiopicrin

Gentiopicrin is an API impurity reference standard carrying the CAS registry number 20831-76-9. Its molecular formula is C16H20O9 and its molecular weight is 356.32 g/mol. Alternative names: Gentiopicroside and gentiopicorside.

The product is provided as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

As a characterised impurity of the parent drug substance, it is used for analytical method development, method validation (AMV) and routine quality-control testing, and it supports ANDA and DMF regulatory filings. It is used across pharmaceutical manufacturing and academic and industrial research.

Available in 10 mg, 25 mg, 50 mg and 100 mg packs, Gentiopicrin is dispatched with a Certificate of Analysis (COA) to destinations worldwide.
