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 electro-optic materials and organic semiconductors due to its ability to form conjugated systems. Its aminophenoxy structure makes it suitable for polymerization reactions, particularly in high-performance polymers like polyimides and polyamides, where it contributes to thermal stability and mechanical strength. Additionally, explored in pharmaceutical research as a building block for bioactive compounds and in materials science for sensors and nonlinear optical devices.
