Description

General description

Ethoxyquin (EQ), an aromatic compound, is an antioxidant mostly used in animal and fish feeds. It is seen to inhibit carcinogenic effects of polycyclic aromatic hydrocarbons. Oxidation initiated by air, light or transition metals in unsaturated lipids can be stopped from propagation by EQ.

Application

EQ has been used as external standard in the determination of EQ and its major metabolite from Atlantic salmon tissues using HPLC with fluorescence detector.
