Used as a key intermediate in the synthesis of sulfonylurea herbicides, particularly in the production of active ingredients that inhibit acetolactate synthase (ALS) in plants. Its structure enables the development of compounds effective in controlling broadleaf weeds and grasses in crops like rice and wheat. Due to its chloropyrazinyl moiety, it contributes to enhanced selectivity and potency in herbicidal formulations. Also explored in agrochemical research for developing next-generation plant growth regulators with improved environmental stability.
