Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure supports the construction of heterocyclic frameworks common in drug discovery. It is also employed in the preparation of fluorescent dyes and optoelectronic materials due to its ability to participate in conjugated systems. In research, it serves as a building block for novel pyrimidine derivatives with potential antimicrobial and anticancer activities.
