About Raubasine

Raubasine is an API reference standard carrying the CAS registry number 483-04-5. Its molecular formula is C21H24N2O3 and its molecular weight is 352.4 g/mol. Common synonyms include Ajmalicine and delta-Yohimbine.

The product is provided 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. Buyers come mainly from pharmaceutical manufacturing and academic and industrial research.

We offer Raubasine in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
