Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the production of pyrazole derivatives which exhibit biological activity. It serves as a key building block in heterocyclic chemistry due to its α,β-unsaturated carbonyl structure, enabling Michael addition and cyclization reactions. Commonly applied in the development of dyes, fluorescent probes, and UV-absorbing compounds owing to its conjugated system. Also utilized in organic synthesis for constructing complex molecules through selective functional group transformations.
