4-Bromo-3-fluorobenzonitrile is a fluorobenzonitrile that is used in the preparation of ethylene. This chemical can also be used in the synthesis of pharmaceuticals and dyes. 4-Bromo-3-fluorobenzonitrile has been shown to have antimutagenicity and DNA repair abilities, which are due to its ability to inhibit carcinogen metabolism by binding to the enzyme cytochrome P450 2E1. 4-Bromo-3-fluorobenzonitrile also prevents cross linking of collagen by reacting with amino groups on lysine residues, which leads to a decrease in cardiac toxicity.
