Used primarily as a monomer in the synthesis of polythioesters, which exhibit unique thermal and mechanical properties suitable for specialty polymers. Its sulfur-containing backbone provides enhanced flexibility and chemical resistance, making it valuable in developing advanced materials for coatings, adhesives, and biodegradable plastics. Also investigated for use in lithium-ion battery electrolytes due to the sulfur moiety’s ability to improve ionic conductivity and electrode stability. Additionally, serves as a building block in organic synthesis for sulfur-rich heterocyclic compounds with potential pharmaceutical applications.
