3-Fluorophenylmagnesium bromide solution
3-Fluorophenylmagnesium bromide solution (CAS: 17318-03-5; FC 6H4MgBr) is an organometallic compound supplied by Tech Serve Solutions. This Grignard reagent, with a molecular weight of 199.30, is primarily utilised in chemical synthesis. It is supplied as a 0.5 M solution in Tetrahydrofuran (THF), requiring storage at 2-8°C due to its reactivity. Its properties make it valuable for introducing the 3-fluorophenyl group in various organic transformations.

Organometallic Synthesis
As a Grignard reagent, 3-Fluorophenylmagnesium bromide solution is a versatile nucleophile for carbon-carbon bond formation in organic synthesis. It reacts with electrophiles such as aldehydes, ketones, esters, and epoxides to construct more complex molecular architectures.
Fluorinated Aromatic Compound Synthesis
This reagent serves as a key building block for introducing the 3-fluorophenyl moiety into organic molecules. Fluorinated compounds are of significant interest in pharmaceuticals, agrochemicals, and material science due to their unique electronic and lipophilic properties.
Pharmaceutical Intermediate Preparation
It can be employed in the multi-step synthesis of active pharmaceutical ingredients (APIs) and drug discovery programmes. The incorporation of fluorine can modulate a drug candidate's metabolic stability, binding affinity, and bioavailability.
