Used as a Grignard reagent in organic synthesis, particularly in the formation of carbon-carbon bonds. It reacts with electrophiles such as aldehydes, ketones, and esters to produce substituted alcohols. Commonly employed in the synthesis of complex organic molecules, including pharmaceuticals and natural products, where the dimethoxyphenyl group is needed as a building block. Its reactivity allows for the introduction of the aromatic ring system under mild conditions, making it valuable in multi-step synthetic routes. Reactions are typically carried out in ether or tetrahydrofuran solvents under anhydrous and oxygen-free conditions.
