Used as an intermediate in the synthesis of azo dyes and pigments, particularly for high-performance industrial colorants. It plays a role in the development of thermochromic and photochromic materials due to its reversible response to temperature and light. Also employed in the formulation of antioxidants for polymers, helping to improve thermal stability and extend material lifespan. Additionally, it has been explored in research settings for its potential as a ligand in metal-organic frameworks (MOFs) with applications in sensing and catalysis.
