Used as an intermediate in the synthesis of pharmaceuticals, particularly in the preparation of heterocyclic compounds with biological activity. It serves in the development of certain analgesic and anti-inflammatory agents due to its ability to undergo cyclization and condensation reactions. Commonly employed in research settings for constructing nitrogen-containing rings such as pyrroles and pyridines. Also utilized in agrochemical synthesis for creating active ingredients in crop protection agents. Its reactivity makes it valuable in organic synthesis for introducing functionalized ester and amide groups.
