Used in the synthesis of fluorescent dyes and optical brighteners due to its naphtholic structure, which contributes to light absorption and emission properties. Also serves as a building block in pharmaceutical intermediates, particularly in the development of compounds targeting neurological and inflammatory conditions. Its amine group allows for easy functionalization, making it valuable in organic synthesis and the preparation of specialty polymers. Additionally, it has been explored in coordination chemistry as a ligand for metal ions in catalytic systems.
