Fexofenadine Impurity F

CAS: 185066-33-5

Impurity F is a metabolite of Fexofenadine. It is an impurity that can be found in the drug product and is used as a research and development standard for impurities. Impurity F has been shown to be a metabolite of Fexofenadine in human liver microsomes, and this metabolite has also been shown to have antihistamine properties. This impurity is used as a pharmacopoeia reference standard for HPLC analysis of fluoroquinolones, but it does not have any therapeutic value.
