Used as an intermediate in the synthesis of phthalocyanine dyes and pigments, particularly for organic semiconductors and photovoltaic materials. Its alkoxy side chains enhance solubility and film-forming properties, making it suitable for solution-processed organic electronic devices such as organic field-effect transistors (OFETs) and organic solar cells. Also employed in the development of sensors and electrochromic devices due to its stable electrochemical behavior and tunable optical properties.
