About Buprenorphine EP Impurity I

Buprenorphine EP Impurity I (CAS 89663-73-0) is a pharmacopeial impurity of Buprenorphine offered by Vaqora Chemicals. Its molecular formula is C28H37NO3 and its molecular weight is 435.6 g/mol. It is also known as Buprenorphine - Impurity I (PSY).

It is supplied as a solid. Keep the vial tightly closed, protected from light and humidity, at the temperature stated on the Certificate of Analysis. Good laboratory practice and suitable PPE are recommended during handling.

As a characterised impurity of Buprenorphine, 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.
