Used primarily as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antipsychotic drugs. It plays a crucial role in the development of phenothiazine derivatives, which are widely utilized in treating mental health disorders such as schizophrenia and bipolar disorder. Additionally, it finds application in organic light-emitting diodes (OLEDs) due to its electron-donating properties, enhancing the efficiency of light emission in electronic displays. Its stability and electron-rich structure also make it valuable in research for advanced materials and photochemical studies.
