Used as an intermediate in the synthesis of dyes and fluorescent whitening agents, particularly in textile and paper industries. Also serves as a building block in pharmaceutical research for developing compounds with potential biological activity, including antimicrobial, antiviral, and anticancer agents. Its aromatic and heterocyclic structure makes it valuable in organic synthesis and material science for designing sensors or optoelectronic materials. Additionally, utilized in research laboratories to create libraries of diverse compounds for biological activity screening.
