Used as a key intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. Its thiol and ester functional groups allow for versatile reactivity, enabling conjugation reactions and the formation of sulfur-containing compounds. Commonly employed in polymer chemistry to introduce thiol functionality into copolymers, enhancing adhesion and crosslinking properties. Also utilized in the development of specialty monomers for UV-curable coatings and resins. Its ability to participate in Michael addition reactions makes it valuable in the synthesis of fine chemicals and functional materials.
