Used primarily as an intermediate in the synthesis of phthalocyanine dyes and pigments, which are widely applied in the production of inks, coatings, and plastics. It also serves as a key building block in the manufacture of advanced materials, including organic semiconductors and photovoltaic cells, due to its ability to form stable, conjugated structures. Additionally, it finds application in the development of agrochemicals and pharmaceuticals, where its chemical properties contribute to the creation of biologically active compounds. Its role in organic synthesis is significant, particularly in reactions involving nitrile groups and aromatic systems.
