About Captopril EP Impurity N

Vaqora Chemicals supplies Captopril EP Impurity N, a pharmacopeial impurity of Captopril registered under CAS number 65134-74-9. Its molecular formula is C8H14O4S2 and its molecular weight is 238.3 g/mol. The IUPAC name is (2S)-3-[[(2S)-2-carboxypropyl]disulfanyl]-2-methylpropanoic acid. It is also known as Captopril Impurity N or Captopril - Impurity N.

The product is provided 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 Captopril, 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.
