Used as a key intermediate in the synthesis of sulfonylurea herbicides, particularly in agricultural chemicals targeting broadleaf weeds and grasses in crops like rice, wheat, and corn. It plays a crucial role in inhibiting plant acetolactate synthase (ALS), an enzyme essential for bran chain amino acid synthesis, leading to arrested growth and death of susceptible weeds. Its derivatives exhibit high potency at low application rates, making them effective in modern selective herbicide formulations. Also investigated for use in eco-friendly pest management strategies due to low mammalian toxicity and favorable environmental degradation profiles.
