Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Its reactive chloromethyl and phenolic groups allow for easy functionalization, making it valuable in constructing sulfone-based compounds. It is employed in the development of active ingredients in herbicides and fungicides due to the stability and bioavailability imparted by the sulfonyl linkage. Additionally, it serves in the preparation of polymer modifiers and crosslinking agents, enhancing thermal and chemical resistance in resins. Its structure supports use in medicinal chemistry for designing enzyme inhibitors, particularly in kinase-targeted therapies.
