4-Fluorophenylmagnesium bromide solution
4-Fluorophenylmagnesium bromide solution (CAS: 352-13-6) is an organometallic reagent with the linear formula FC₆H₄MgBr and a molecular weight of 199.30 g/mol. Supplied as a 1.0 M solution in Tetrahydrofuran (THF), this flammable liquid is primarily utilised in organic synthesis for introducing the 4-fluorophenyl group into various molecules. Its reactivity makes it a valuable tool in the creation of complex organic structures for research and development.

Grignard Reagent for C-C Bond Formation
4-Fluorophenylmagnesium bromide solution serves as a versatile Grignard reagent in organic synthesis. It readily reacts with electrophiles such as aldehydes, ketones, esters, and epoxides to form new carbon-carbon bonds, facilitating the construction of more complex fluorinated organic compounds.
Synthesis of Fluorinated Pharmaceuticals
The incorporation of fluorine atoms can significantly alter the pharmacokinetic and pharmacodynamic properties of drug molecules. This reagent is employed in the synthesis of intermediates and active pharmaceutical ingredients (APIs) where a 4-fluorophenyl moiety is a key structural feature.
Preparation of Agrochemicals
Fluorinated compounds are also prevalent in the agrochemical industry. 4-Fluorophenylmagnesium bromide solution can be used in the development and production of pesticides, herbicides, and fungicides that benefit from the unique properties imparted by fluorine.
Research and Development Tool
As a specialised organometallic compound, it is indispensable in academic and industrial research laboratories for exploring novel synthetic routes and developing new materials or compounds with specific electronic or physical properties.
