Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. Its structure, featuring a methylsulfonyl group at the 2-position and a carboxylic acid at the 4-position on the pyridine ring, supports the formation of biologically active molecules that target specific signaling pathways in tumor cells. Also employed in agrochemical research for designing herbicides and plant growth regulators due to its ability to enhance molecular stability and solubility in formulation development.
