About Flumazenil EP Impurity D

Flumazenil EP Impurity D (CAS 78755-80-3) is a pharmacopeial impurity of Flumazenil offered by Vaqora Chemicals. Its molecular formula is C10H9FN2O2 and its molecular weight is 208.19 g/mol. Systematically, it is named 7-fluoro-4-methyl-1,3-dihydro-1,4-benzodiazepine-2,5-dione. It is also known as Flumazenil - Impurity D or Flumazenil dione.

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 Flumazenil, it is used for analytical method development, method validation (AMV) and routine quality-control testing, and it supports ANDA and DMF regulatory filings. Buyers come mainly from 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.
