Used as a key intermediate in the synthesis of phthalocyanine dyes and pigments, which are valued for their intense color and stability in inks, coatings, and plastics. Also employed in the development of organic semiconductors and fluorescent probes due to its electron-rich structure and ability to form conjugated systems. Its reactivity makes it suitable for use in sensors and optoelectronic devices, including solar cells. Additionally, it finds application in the preparation of pharmaceuticals and agrochemicals through functionalization of the amino and nitrile groups, as well as in research on nanomaterials and photocatalysis for environmental remediation.
