About Doxepin EP Impurity B

Vaqora Chemicals supplies Doxepin EP Impurity B, a pharmacopeial impurity of Doxepin registered under CAS number 4504-88-5. Formula C19H23NO2, molecular weight 297.4 g/mol. Systematically, it is named 11-[3-(dimethylamino)propyl]-6H-benzo[c][1]benzoxepin-11-ol. It is also known as Doxepin Hydrochloride - Impurity B or Doxepin Related Compound B.

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. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

As a characterised impurity of Doxepin, 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.
