Used in organic synthesis, particularly in the preparation of heterocyclic compounds. It serves as a key intermediate in the development of pharmaceuticals, especially for compounds with potential biological activity. Its structure is valuable in the synthesis of indole derivatives, which are often explored for their therapeutic properties, such as anti-inflammatory, antimicrobial, or anticancer effects. Additionally, it can be utilized in the creation of agrochemicals and dyes due to its reactivity and ability to form complex structures.
