Used as an intermediate in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. Its thiol and ester functional groups allow for versatile chemical modifications, making it valuable in constructing complex molecules. Commonly employed in the preparation of biologically active compounds, including protease inhibitors and other therapeutic agents. Also utilized in polymer chemistry as a chain transfer agent to control molecular weight during radical polymerization processes. Its ability to participate in thiol-ene reactions makes it useful in materials science for crosslinking and surface functionalization.
