Used primarily as an intermediate in organic synthesis, this compound plays a key role in the preparation of pharmaceuticals and agrochemicals. Its reactivity allows for the introduction of pyrrole-based structures into larger molecules, which is valuable in drug development. It is also employed in the synthesis of functionalized heterocycles, which are important in the creation of bioactive compounds and specialty materials. Due to the presence of the chloroethyl group, it can act as an alkylating agent, facilitating ring closure or chain extension in complex molecule assembly.
