Cis-Beta-Asarone

About Cis-Beta-Asarone

Cis-Beta-Asarone is an API impurity reference standard carrying the CAS registry number 5273-86-9. The compound has the formula C12H16O3, corresponding to a molecular weight of 208.25 g/mol. Its systematic (IUPAC) name is 1,2,4-trimethoxy-5-[(Z)-prop-1-enyl]benzene. Common synonyms include beta-Asarone and (Z)-Asarone.

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. Under GHS it is labelled “Warning”, so handle it with suitable PPE and consult the SDS.

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. Buyers come mainly from pharmaceutical manufacturing and academic and industrial research.

Standard pack sizes are 10 mg, 25 mg, 50 mg and 100 mg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
