Used as a key intermediate in organic synthesis, particularly in the preparation of biologically active compounds. It serves in the construction of nitrogen-containing heterocycles, which are common structural motifs in pharmaceuticals and agrochemicals. Its reactivity allows for ring expansion and annulation reactions, making it valuable in the development of novel drug candidates. Also employed in the synthesis of cyclopentane-based analogs for medicinal chemistry research, especially in projects targeting enzyme inhibitors or central nervous system agents.
