Used as an intermediate in the synthesis of dyes and fluorescent whitening agents due to its aromatic structure and hydroxyl group reactivity. Employed in the production of specialty polymers and optical brighteners for textiles and paper. Also serves as a building block in organic synthesis for pharmaceuticals and agrochemicals, where the naphthalene core enhances lipophilicity and binding properties. Its derivatives are explored in materials science for developing organic semiconductors and luminescent compounds.
