Primidone EP Impurity A

About Primidone EP Impurity A

Primidone EP Impurity A is a pharmacopeial impurity of Primidone carrying the CAS registry number 7206-76-0. Formula C11H14N2O2, molecular weight 206.24 g/mol. Systematically, it is named 2-ethyl-2-phenylpropanediamide. Common synonyms include Primidone Related Compound A and Primidone - Impurity A.

It is supplied as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

As a characterised impurity of Primidone, it is used for analytical method development, method validation (AMV) and routine quality-control testing, and it supports ANDA and DMF regulatory filings. It is used across pharmaceutical manufacturing and academic and industrial research.

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