Used as an intermediate in the synthesis of dyes and fluorescent whitening agents due to its aromatic structure and reactive hydroxyl group. Its chlorinated naphthalene backbone allows for further functionalization in organic reactions, making it valuable in the development of specialty chemicals. Also explored in research for potential use in optoelectronic materials because of its conjugated system and light-emitting properties when modified. Limited solubility in water but dissolves well in organic solvents, which supports its use in solvent-based industrial processes.
