6-Hydroxy-3,4-dihydro-2(1H)-quinolinone

Its uses extend to material science (OLEDs, polymers) and as a scaffold in general organic synthesis, leveraging its quinoline structure for creating various bioactive molecules and functional materials. 6-Hydroxy-3,4-dihydro-2(1H)-quinolinone is a crucial pharmaceutical intermediate used as a building block for synthesizing drugs, most notably Cilostazol (for intermittent claudication) and for developing novel agents like MAO-B inhibitors, anticonvulsants, and anticancer drugs (HDAC inhibitors).
