Withanoside V

About Withanoside V

Withanoside V is a high-purity reference standard of Withaferin A carrying the CAS registry number 256520-90-8. With the molecular formula C40H62O14, it has a molar mass of 766.9 g/mol.

It is supplied as a solid. Keep the vial tightly closed, protected from light and humidity, at the temperature stated on the Certificate of Analysis. Handle it with standard laboratory precautions and appropriate personal protective equipment.

Laboratories use this Withaferin A standard for identity and assay testing, system suitability checks and method validation supporting ANDA and DMF filings. It is used across 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.
