About Ethotoin

Ethotoin is an API reference standard carrying the CAS registry number 86-35-1. Formula C11H12N2O2, molecular weight 204.22 g/mol. The IUPAC name is 3-ethyl-5-phenylimidazolidine-2,4-dione. It is also known as Peganone or 3-Ethyl-5-phenylhydantoin.

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 “Warning”, 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. It is used across pharmaceutical manufacturing and academic and industrial research.

Vaqora Chemicals supplies Ethotoin in 10 mg, 25 mg, 50 mg and 100 mg packs, each shipped with a Certificate of Analysis (COA), and exports worldwide.
