Used as an intermediate in the synthesis of azo dyes and pigments, particularly for high-performance colorants in textiles and printing inks. Its structure supports the development of compounds with strong lightfastness and color intensity. Also employed in research for developing photoresponsive materials due to the azo group’s ability to undergo trans-cis isomerization upon light exposure. Shows potential in coordination chemistry as a ligand for transition metal complexes, which may have catalytic or sensor applications.
