Used as an intermediate in the synthesis of dyes and fluorescent compounds due to its ability to undergo substitution reactions. It serves in the preparation of naphthyl-based dyes and pigments, particularly in azo dyes where the bromine group facilitates coupling reactions. Also employed in the development of certain pharmaceuticals and agrochemicals, where the naphthalene backbone provides structural stability. Its hydroxyl and bromo functional groups allow for derivatization in organic synthesis, making it valuable in research laboratories for building complex aromatic molecules. Additionally, it has been explored in the formulation of some photochemical sensors and optical brighteners.
