Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of local anesthetics and antihistamines. It serves as a quaternary ammonium precursor, enabling the introduction of dimethylaminoethyl groups into larger molecules. Commonly employed in the preparation of cholinergic agents and muscle relaxants due to its ability to modify biological activity through alkylation. Also utilized in organic synthesis for creating ionic liquids and functionalized polymers. Its reactivity makes it valuable in the development of specialty chemicals and agrochemicals.
