Used as an intermediate in the synthesis of phthalocyanine dyes, which are widely applied in the production of pigments for inks, coatings, and plastics. It is also utilized in the development of organic semiconductors for electronic devices, such as solar cells and transistors. Additionally, it serves as a key building block in the preparation of advanced materials for optoelectronic applications, including light-emitting diodes (LEDs) and sensors. Its role in the creation of metal-organic frameworks (MOFs) further extends its use in gas storage and separation technologies.
