Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective functionalization, making it valuable in creating compounds with high biological activity. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to build complex heterocyclic systems. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its ability to enhance molecular binding and stability. Its aldehyde group enables easy conversion into various derivatives like alcohols, acids, or imines, expanding its utility in medicinal chemistry.
