About Cantharidin

Cantharidin is an API reference standard carrying the CAS registry number 56-25-7. The compound has the formula C10H12O4, corresponding to a molecular weight of 196.2 g/mol. Systematically, it is named (1S,2R,6S,7R)-2,6-dimethyl-4,10-dioxatricyclo[5.2.1.02,6]decane-3,5-dione. Alternative names: Cantharone and Cantharides camphor.

The product is provided as a solid. Keep the vial tightly closed, protected from light and humidity, at the temperature stated on the Certificate of Analysis. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Laboratories use this the parent drug substance standard for identity and assay testing, system suitability checks and method validation supporting ANDA and DMF 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.
