About Nimodipine EP Impurity C

Nimodipine EP Impurity C is a pharmacopeial impurity of Nimodipine carrying the CAS registry number 70172-96-2. Formula C21H26N2O8, molecular weight 434.4 g/mol. Its systematic (IUPAC) name is bis(2-methoxyethyl) 2,6-dimethyl-4-(3-nitrophenyl)-1,4-dihydropyridine-3,5-dicarboxylate. It is also known as Cilnidipine IP Impurity A or Nimodipine - Impurity C.

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.

This Nimodipine impurity supports analytical method development and validation (AMV), batch release testing and the impurity sections of ANDA and DMF 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.
