This chemical is primarily utilized in the synthesis of organic compounds, particularly in the development of photochromic materials. It serves as a key intermediate in the production of molecules that exhibit light-induced reversible color changes, making it valuable in applications like smart windows, optical data storage, and light-sensitive lenses. Additionally, it is employed in the pharmaceutical industry for the creation of drug candidates, especially those targeting neurological and psychiatric disorders, due to its structural relevance in bioactive molecules. Its nitro and indolinone groups make it a versatile building block in organic synthesis for constructing complex chemical architectures.
