Used as a key intermediate in the synthesis of various pharmaceuticals, particularly in the development of anticonvulsant and antimicrobial agents. It serves as a building block for indole-based compounds, which are important in medicinal chemistry due to their biological activity. Commonly employed in the preparation of Schiff bases and hydrazones, which are studied for their potential anticancer and anti-inflammatory properties. Also utilized in the fabrication of dyes and pigments, and in research for developing new heterocyclic compounds with tailored functional properties.
