Used as an intermediate in the synthesis of functional dyes, particularly phthalocyanine dyes, which are valued for their intense color and stability in pigments and inks. Also serves as a building block in the preparation of organic semiconductors and photoconductive materials used in imaging devices and photocopiers. Its structure supports conjugation and electron delocalization, making it suitable for applications in optoelectronic devices and as a precursor in the development of conductive polymers. Additionally, it has been explored in research for corrosion inhibitors and in the design of sensors due to its coordination ability with metal ions.
