Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic acetylcholine receptor modulators. It serves as a quaternary pyridinium salt that facilitates alkylation reactions in heterocyclic chemistry. Commonly employed in the preparation of bioactive molecules and ionic liquids due to its stability and reactivity in nucleophilic substitution. Also utilized in research settings for constructing pyridinium-based compounds with potential antimicrobial or neuroactive properties.
