Used as an intermediate in organic synthesis, particularly in the production of heterocyclic compounds and pharmaceuticals. It serves as a building block in the development of kinase inhibitors and other biologically active molecules. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its amide and amine functional groups, which facilitate molecular diversification. Also utilized in the synthesis of dyes and fluorescent probes for biochemical labeling. Its aromatic and polar characteristics make it suitable for solid-phase synthesis and combinatorial chemistry applications.
