Used as a precursor in the synthesis of nicotinamide adenine dinucleotide (NAD) analogs, this compound plays a role in biochemical research involving enzyme cofactors. It is also employed in the development of ionic liquids due to its stable pyridinium structure, which can enhance catalytic efficiency in organic transformations. Additionally, it serves as a building block in the preparation of functionalized pyridinium salts for studies in electrochemistry and sensor design.
