Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antihypertensive and anti-inflammatory agents. Its structure allows for functionalization at multiple sites, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in Suzuki and Wittig reactions to form extended conjugated systems for drug candidates. Also utilized in the preparation of biologically active molecules targeting central nervous system disorders. Its aldehyde group facilitates easy conversion into acids, alcohols, or imines, enhancing its versatility in synthetic pathways.
