Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. The iodine substituent allows for cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex molecules. The ester group can be hydrolyzed or transformed into other functional groups, adding versatility in synthetic pathways. Commonly employed in the development of nicotinate-based bioactive compounds, including potential drug candidates targeting central nervous system disorders or metabolic diseases. Also utilized in materials science for designing nitrogen-containing heterocyclic frameworks.
