Used as a Grignard reagent in organic synthesis to introduce the 3-fluorophenyl group into various molecules. It is particularly valuable in the preparation of pharmaceuticals and agrochemicals, where the fluorine atom can enhance biological activity and metabolic stability. The reagent is also employed in the synthesis of complex organic compounds, including polymers and fine chemicals, due to its ability to form carbon-carbon bonds efficiently. Handling requires strict control of moisture and air to maintain reactivity.
