About Dienestrol

Dienestrol (CAS 84-17-3) is a high-purity reference standard of Dienestrol offered by Vaqora Chemicals. Its molecular formula is C18H18O2 and its molecular weight is 266.3 g/mol. Systematically, it is named 4-[(2E,4E)-4-(4-hydroxyphenyl)hexa-2,4-dien-3-yl]phenol. Alternative names: Dienoestrol and Dehydrostilbestrol.

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 Dienestrol 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.

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