Used in the synthesis of coumarin-based derivatives for pharmaceutical research, particularly in developing compounds with antioxidant and anti-inflammatory properties. It serves as an intermediate in the preparation of fluorescent dyes and optical brighteners due to its ability to absorb and emit light in the UV-visible range. Also employed in studies related to enzyme inhibition, especially in models targeting metabolic and neurodegenerative disorders. Its structure supports derivatization for use in medicinal chemistry and material science applications.
