Used as a key intermediate in the synthesis of fluorescent dyes and optical brighteners due to its extended aromatic structure and reactive halogen groups. The bromo and fluoro substituents allow for selective cross-coupling reactions, making it valuable in the development of advanced organic materials for imaging and sensor technologies. Also employed in the preparation of naphthoquinone derivatives with potential biological activity, supporting research in medicinal chemistry. Its hydroxyl group facilitates conjugation or derivatization for use in dyes with enhanced photostability and color intensity.
