Used as an intermediate in the synthesis of dyes and pigments, particularly for azo dyes where it acts as a coupling component to enhance color fastness. It is also employed in the production of optical brighteners for textiles and paper due to its ability to absorb UV light and emit blue fluorescence. Additionally, it serves as a building block in agrochemicals, contributing to the development of certain herbicides and plant growth regulators. Its reactivity allows for easy functionalization in heterocyclic chemistry, making it valuable in research and development of new organic compounds.
