Used in organic synthesis as a key intermediate for producing various biologically active compounds. It plays a role in the development of pharmaceuticals, particularly in the synthesis of indole-based drugs that exhibit anti-inflammatory, antimicrobial, and antitumor properties. Additionally, it is utilized in the creation of agrochemicals, such as pesticides and herbicides, due to its structural versatility. In research, it serves as a building block for studying indole derivatives and their potential applications in medicinal chemistry. Its unique structure also makes it valuable in the development of fluorescent dyes and sensors for biochemical studies.
