Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of herbicides, fungicides, and plant growth regulators. Its structure allows for easy functionalization, making it valuable in creating active ingredients that target specific enzymes in pests or weeds. Also employed in research for developing novel compounds with biological activity, including antifungal and antibacterial agents. Its chloro and carboxylic acid groups provide reactive sites for coupling reactions in medicinal chemistry.
