Used primarily as an intermediate in the synthesis of dyes and pigments, especially in the production of high-performance phthalocyanine dyes and pigments which are valued for their intense color, stability, and resistance to heat and light. It plays a key role in the preparation of phthalocyanine blue and green pigments widely used in coatings, inks, plastics, and textiles. Also serves as a building block in the development of functional materials such as organic semiconductors, sensors, and optoelectronic devices due to its electron-deficient aromatic structure. Its nitro group allows for further chemical modifications, enabling tailored derivatives for specific industrial and research applications.
