Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and antibacterial agents. Its reactive aldehyde group enables coupling reactions to form more complex molecules, making it valuable in medicinal chemistry. Also employed in agrochemical research for designing novel pesticides due to its halogenated pyrazine structure, which can enhance bioactivity and stability. Additionally, it serves as a building block in the preparation of functional dyes and electronic materials where nitrogen-rich heterocycles are required.
