S,S'-(thiobis(4,1-phenylene)) bis(2-methylprop-2-enethioate); CAS No.: 129283-82-5; S,S'-(thiobis(4,1-phenylene)) bis(2-methylprop-2-enethioate). PROPERTIES: This sulfur-linked bis(phenylene) bis(thioester) features molecular formula C??H??O?S? with molecular weight 392.52 g/mol. It typically exists as a white crystalline powder. Soluble in non-polar and slightly polar organic solvents like hexanes and ethyl acetate. Melting point approximately 80-85 C. Exhibits IR absorption for ester (~1750 cm??) and C-S stretches (~750-600 cm??). Thermogravimetric analysis indicates decomposition above 180 C under nitrogen. For optimal stability, store at 2-8 C in tightly sealed containers with desiccant, protected from light. The compound may cause mild skin irritation and serious eye damage; therefore, standard laboratory safety precautions including protective clothing and eye protection are recommended during handling. APPLICATIONS: As a sulfur-linked bis(phenylene) bis(thioester), S,S'-(thiobis(4,1-phenylene)) bis(2-methylprop-2-enethioate) is predominantly utilized in the synthesis of thiol-ene polymers. It serves as a key monomer in preparing crosslinked polymer networks with tunable mechanical properties, where the thioester groups undergo radical-mediated crosslinking reactions as demonstrated in polymer chemistry research (Macromolecules). Additionally, the compound participates in the development of photolithographic resists for microelectronics, where the thioester functionality enables photopatterning via controlled radical polymerization (Journal of Polymer Science). In materials science, it functions as a monomer for preparing self-healing polymers, where the dynamic thioester bonds facilitate autonomous repair of mechanical damage (Advanced Materials).
