Used as an intermediate in the synthesis of agricultural chemicals, particularly herbicides and plant growth regulators. Its structure allows for modification to enhance selectivity and efficacy in controlling broadleaf weeds. Commonly employed in the development of sulfonylurea-type herbicides, where it contributes to the inhibition of acetolactate synthase (ALS), a key enzyme in amino acid biosynthesis in plants. Also utilized in research for designing new crop protection agents due to its stability and reactivity in coupling reactions.
