A meta-oriented, rigid aromatic dithiol combining two benzylic –SH groups on a 1,3-phenylene spacer. The vicinal thiols enable high-density cross-linking, metal chelation and orthogonal click chemistry, making the molecule a strategic building block for:
High-refractive-index poly(aryl sulfide) resins (nD ≈ 1.70) for 5G lens substrates and OLED encapsulation films;
Self-assembled monolayers (SAMs) on gold or silver, providing densely packed, defect-free films for SERS biosensors and mercury-ion optrodes;
Metal-organic frameworks (MOFs) – soft S-donor sites together with hard carboxylate co-ligands construct heterometallic cages for gas storage (CO₂, CH₄) and catalysis;
Photoresponsive & drug-delivery systems – recent patents utilise its 1,3-bis(mercaptomethyl) pattern to build light-cleavable linkers and redox-sensitive nanoparticles ;
Cross-linker for epoxy/PU systems, imparting enhanced chemical resistance and flexibility at 1–3 wt % loading.
Store under nitrogen at 2–8 °C, away from oxidants.
