About Levetiracetam EP Impurity A

Levetiracetam EP Impurity A (CAS 67118-31-4) is a pharmacopeial impurity of Levetiracetam offered by Vaqora Chemicals. Its molecular formula is C8H13NO3 and its molecular weight is 171.19 g/mol. Systematically, it is named 2-(2-oxopyrrolidin-1-yl)butanoic acid. Common synonyms include Levetiracetam Impurity A and Levetiracetam - Impurity A.

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.

As a characterised impurity of Levetiracetam, 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.

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.
