| Use Pattern |
| Suzuki–Miyaura Coupling Reactions Widely used as a boronic acid building block in palladium-catalyzed cross-coupling reactions with aryl or vinyl halides. Enables the synthesis of pyrimidine-containing biaryl and heteroaryl compounds |
| Pharmaceutical Intermediates Serves as a key intermediate in the preparation of drug candidates, especially kinase inhibitors, antiviral agents, and anticancer compounds that incorporate the pyrimidine motif. |
| Agrochemical Synthesis Applied in the design and synthesis of heteroaryl derivatives used in herbicides, fungicides, and insecticides |
| Material Science Sometimes employed in the development of functional materials, such as conjugated heteroaryl polymers or ligands for coordination chemistry. |
| Medicinal Chemistry Research Useful for structure–activity relationship (SAR) studies, introducing pyrimidine groups into molecules to modulate biological activity and improve binding affinity. |
