Used as an intermediate in the synthesis of biologically active compounds, particularly in the development of pharmaceutical agents targeting enzyme inhibition and anti-inflammatory pathways. Its structural features enable participation in key reactions for constructing complex heterocyclic systems. Commonly applied in medicinal chemistry research for designing protease inhibitors and kinase modulators. Also utilized in agrochemical research for developing novel pesticides with improved selectivity and efficacy. Its conjugated system and functional groups allow for further derivatization in structure-activity relationship (SAR) studies.
