Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of herbicides and plant growth regulators. It plays a role in the production of certain chlorinated pyrazine derivatives that exhibit biological activity, making it valuable in agrochemical research. Its structure allows for further functionalization, enabling the creation of compounds with selective activity in crop protection. Additionally, it has been explored in the design of novel antimicrobial agents due to the inherent reactivity of the dichloropyrazine core.
