Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Its reactive chloroethyl group and thiazole ring make it valuable in constructing more complex molecules, especially in the development of active ingredients in crop protection agents and biologically active compounds. It can participate in alkylation reactions and is useful in introducing the thiazole moiety into larger structures, which is a common feature in several medicinal agents. Due to its reactivity, it requires careful handling in industrial processes.
